As far as I know, tank armor in ww2 was tempered to be soft to absorb the energy a bit. Tempering to too hard would make the armor brittle. I could see hard armor like this working well as a skin on top of softer steel...Im sure the modern engineers have worked all this out...
That's kind of the way battleship armor such as Class A face hardened steel is designed, it's also always backed by a softer steel splinter protection layer to catch any spalling
This video provides a critical example of the importance of making sure that your protective measures can stand up to sudden fractures or shatters at the upper end of the scale of the forces being used for testing.
Nice and interresting video 👍 However, it was a bit ironic that chipboard plates were used as protection when testing state of the art armour to destruction 🤔

@@greg77389 I bend steel pretty often. bending a piece of 0.25 inch mild steel 90 degrees in a 2 inch die makes it heat several degrees and become noticeably warm to the touch.
@@Corsa15DT except those people that know how spheres work. Unlike on any other shape, on a circle/sphere there are no weak points because stresses are distributed equally along the surface. Theres no corners or edges so there cant be a single weak point.
All of this makes you actually frigthened of the things that these armors stand against. After all, the armor of WW2 was already tough and that was already difficult to deal with. But the modern one that survived a lot more punishment makes you actually impressed about what modern anitarmor weapons can actually DO.
Do not forget that the majority of modern tank armor uses higher quality alloys than what was shown here, and also usually is layered with some form of composite (usually advanced ceramics or in the case of the abrams, spent uranium-derived materials) that works in conjunction with the high end alloys to slow, catch, and disperse the energy of, modern super high velocity anti-tank rounds, as well as handle the heat jets from modern shaped charges. A T-90M, Abrams of any model, or a Leopard 2 of any model would simply sneer at any cannon or AP round that WWII could feasibly throw at them.
@@willkenny5687 "A T-90M, Abrams of any model, or a Leopard 2 of any model would simply sneer at any cannon or AP round that WWII could feasibly throw at them." From the front? Most definitely. From the sides? Then I would be a bit concerned. From the back or top? They're a goner. Even ww1 artillery would go though the roof of a modern tank like a hot knife through butter. Also, your tank list is weird, why list the T-90M, which is a top of the line tank, along with any model of Abrams and Leopard 2? An original Abrams or Leopard 2 is no where close to a T-90M, they are more like a T-72B but with a much worse gun in the case of the Abrams who originally only mounted the near obsolete L7 105mm riffled gun. The soviets where way ahead when it comes to guns as they already moved to a 115mm smoothbore gun back in the 60s when they made the T-62. Even the latest version of Abrams would probably be at a disadvantage against the T-90M as the Abrams tank has bigger weakpoint in the upper glacis. In a hull down fight, it's anyone's guess who has the better chance of penning the other since both armor compositions are unknown to the public at this point.
@@willkenny5687 Тут дело не только в качестве. Похоже сам подход к созданию броневой стали изменился. Раньше считалось, что броня должна обладать высокой вязкостью чтобы снаряд застревал в такой броне примерно как палец в пластилине а сама броня при этом бы не разлеталась на кусочки как во втором случае (чтобы экипаж танка от осколков не пострадал). Сейчас же, похоже, опять пришли к высокой твердости брони дабы броня сама по себе сопротивлялась какому-либо внедрению твердого материала (сердечника снаряда) а осколки в случае разрушения, видимо, должен удерживать противоосколочный подбой или какой-то хитрый слой брони из композитного материала.
@@skitidet4302 The latest version of the abrams at a disadvantage against a T-90M? Don’t make me laugh. The M1a1 abrams handled T72s using the same 2a46m main gun as the t90m in iraq, and was never penetrated. I have strong doubts that that situation has changed dramatically enough to put the M1a2sepv3 at substantial risk. The soviets in the 50’s absolutely were leading the way by a lot when it came to tank technology, and the IS-3 was definitely better than anything the allies or axis had at the time, but materials technology has come a long way since then, I have very strong doubts that even its 122mm gun with WWII era ammo could take out a modern mbt. And the reason as to why I included all of those tanks together is because the original M1, the original leopard 2s, and the T90M, all use technology from the 80’s and 90’s, and are thus roughly contemporary if not equivalent.
Fun fact: Old style AP shells weren't actually 'pointed'. They were very much like truncated, shouldered cones. It allowed the shell to penetrate, while alleviating a good bit of the weakness of an acutely angled point. The classical 'bullet' shape was actually just a cap that served to increase the ballistic coefficient and to crush as the projectile made contact to help support the shell so it didn't shatter on impact.
also its the inside of the AP round that did the job, meaning tungsten carbide and explosive detonation based on tests so that once inside a tank it would exploded killing everyone and also disabling the tank as well?
I was really expecting that super-cooled ball to shatter way before the armor.... quite the opposite happened. If they could cool a projectiles tip like that, it would penetrate virtually any armor. heh
The problem with the first test is that spaced and layered armor is meant to bleed energy from the projectile to eliminate its penetration. A constant input of energy, like from the press, is always gonna crack it because that's not what it was meant to defeat
It looks like they made it to break perpendicular to the normal plane of the installed plate. It cracks perfectly horizontally and vertically. Very impressive.
@@NekosaHaruna They only compare "yellow" and "warm" at the same time. The structure of steel is clearly different, while 1940 sends a big hello to 2010. Steel production is not drawing in office programs by "effective" managers.
Exactly, a true comparison, like apples to apples, would be a single piece of forged titanium the same size as the steel piece. This is grapes to apples.
The way that steel blew up at the end was like a giant fragmentation grenade! Pretty scary stuff actually. Now I can see why all of the safety precautions are necessary. I’m very surprised by how much stronger our steel has gotten, I didn’t think there was this much room for improvement.
Part of the reason is because different steels are made for different purposes. The Soviets could have made armor steel similar to AR500 back in the 1940's. in fact, some of their tank armors were even harder, but there's a reason they didn't continue doing this. Tank armor is not supposed to be as hard as possible. Steel is on a spectrum between hardness (ability to resist deformation) and toughness (ability to withstand shock). Too far in either direction would make it bad for the armor. If tank armor was super hard, then it would also be super brittle, and big impacts (like incoming shells) would cause it to shatter super easily. Shards of razor-sharp metal would fly everywhere inside the tank and kill a lot of people.
@@raven4k998With the Titan they used carbon fiber, very strong but when it fails it fails suddenly instead of deforming and bending which could be the difference between getting back to the surface before total failure. I've also seen an example of this in motorcycle racing where a damaged rear wheel made of carbon fiber failed instantly and blew into pieces so they don't use those now haha
Maybe someone can explain why the ball survived after the dunk in liquid nitrogen. I'm willing to guess that the ball actually work-hardened for several millimeters deep, maybe an inch deep? Is this possible? So if the armor was equally work-hardened, it has a shape that was not as strong to withstand the pressure? Internally the armor did not represent an equally tall sphere, for one thing, but has more middle dimension. This has me stumped somewhat.
@@YouKnowTheyExistthere are 2 big reason why this happen. As someone else pointed out the energy was dispersed a lot more with the liquid nitrogen and the shape of the ball will also disperse energy a lot more than a cone, it will stay more on the surface of the ball meaning it wont damage it as much.
@hammerheadxray8152 I was expecting the same thing honestly. My guess as a metallurgist is that the plate already had some cracks initiated in it from the previous test while the ball did not have any stress concentrating flaws. Both materials are brittle given the brittle fracture surface left in the plate but because the plate may have started with more flaws it fractured first.
That… Is sick! The armor fragmented and “exploded” just like a grenade with an insane power. I think this was the most dangerous press video I’ve seen so far. Great show
This video is actually a great example of why tanks shouldn't have too sturdy armor; although this isn't a perfect example, seeing it shatter like that is similar to the phenomenon of 'spalling', which is when armour fractures instead of deforming, causing armour chunks on the inside to break loose, which is _extremely_ hazardous for the crew inside. During WWII the T-34 was notorious for this because they made it overly strong, and therefore brittle.
@@TheEDFLegacy So i guess they need a double layer of armor ? A very strong outer layer and a softer inner layer so that the inner layer stops the fragments of the shattering outer layer. Maybe even an armor plate with gradient hardness where the outside is super hard and it gradually softens to the inside would work ? Oh well since nothing receives better funding than the army and weapons industies, im sure they have thought about that and tried everything :)
@@arjensmit6684 Yep, and this is one of the conventions you see with a lot of modern tanks. The M1 Abrams had depleted uranium as a dense shock absorber. The problem there is that they had to stop using that because of situations where uranium did the uranium thing and irradiated the crew, depleted or not. Other materials are still used, however.
@@hamzagorcevic8443 Yes and no, the "old" armor from 100 yrs. ago is the same material mixture/structure/steel, but back in those days they didn´t have had the steel compound/mixture discovered or researched from today, so that armor from 2010 is "new".
@@hamzagorcevic8443not a metallurgist, but there are better alloys, casting techniques and treatment techniques available to improve the resilience. They are usually secret. Even if available, back in WWII the Soviets might simply not have had the time for all these process as they had to churn out lots of tanks to be able to stop the Axis.
@@KnightRadiant-ip9qw You'd need to accelerate them to the sort of velocity that meteorites move at - 5 miles/8km per second or greater. A rail gun could do that but the ball bearings would be prone to getting squeezed in half by the rail gun so they'd need to be very special ball bearings - an apfsds round from a modern tank gun would be much cheaper.
@@vipertwenty249 I know. I realized that as I was writing. But who knows? Maybe railguns will end up being the launcher for such a type of ammunition in the future.

Because Diamond in insanely hard against cutting force (nothing than another diamond can cut a diamond) but also very weak to percussive impacts and crushing
@@vayalond7203 Yeah, diamond is incredibly abrasion resistant, kinda like the AR500 steel brick that exploded in the video, both are used for things like teeth on a bore drill since they just don't wear away quick at all. Diamond is a 98.07 HRC, while AR500 is among the highest steels at 48.3 HRC. 6061-T6 Aluminium is a 60 HRB, and doesn't have an HRC since its just not in the same category of hardness as steel alloys, for comparison an HRB of 82 rates an HRC of 1, or 120 HRB rates 55 HRC, its due to the different weight and from using a different surface, HRB is measured with a 100kg weight on a 1/16" ball while HRC is a 150kg through a diamond brale indenter. There are steels harder than AR500, even up to 68, but much higher than AR500 seems to be going into specialty alloys that are very difficult and expensive to manufacture. There is also CrCoNi, which rates 468 HV hardness, which is about 46 HRC, but it performed excellently from the looks of things at extremely low temperatures, on the order of a yield strength over 500 MPa under 100K, where a material like 2.25Cr-1Mo, or A387 Grade 22, yielded at about 370 MPa at 100K, 380 MPa at around 20K. Shit, I did it again, I rambled but I typed so much I don't want it to go to waste, so lol sorry for the word vomit XD
I think you may have misunderstood the 'hold my beer' meme- it's supposed to represent when an overconfident person says 'hold my beer' and then quickly gets humiliated by who-or-whatever they had just underestimated. The first example was an old Yosemite Sam cartoon where some yahoo is challenged by Sam and asks someone to 'Hold my beer.' before getting shot to pieces. But, I agree with your intent re: the strength of steel- most people still think, for example, that titanium is both harder than all steels, and stronger, by mass (which it is not) in addition to by volume (which is may be). And, re: diamond... yeah... (hardness has little to do with tensile/compressive/elastic/plastic/etc strength). Cheers !
Holy crap,I thought the metal ball would shatter after being in liquid Nitrogen,I didn't expect everything else around it to break instead(Including the camera!)😂
Putting heat treated steel in liquid nitrogen adds even more hardness (even after it has warmed back up again) Applied Science has a good video on this. BBs are already made to be extremely hard, so I'm not surprised it wrecked the AR500 plate. Obviously brittleness comes into play with dynamic loading so you couldn't expect it to survive being used as a bullet, etc.
@@jhonbus ..it wouldnt work as a bullet... perhaps on a very short distance wher it does not experience much friction and heating... would be interesting to see someone test actually..from 10m to 1km or so... ..and yes just because its already heat threathened (has a martensite electron structure) ... the way electrons move in the material makes it extremely much harder when he electron states r being locked at lower temperatures... but it would be hard to keep a bullet below 80 Kelvin (below -193 deg C), of scientiffic curiousity one could possibly use liquid nitrogen for 20 mins and then use liquid Helium pressurized (-4 Kelvins), it probably wouldent be extremely hard to build a pressure cylinder to pressurize a container for this guys... A SHARP WARNING!, LIQUID HELIUM IS VERY DANGEROUS TO PLAY AROUND WITH, IN IT LIQUID STATE IT CAN EXPAND (EXPLODE) WITH A FORCE GREATER THAN TNT!...
Ball bearings are made of 52100 steel. Around 1% carbon. They can be fairly hard. There’s more hardenable steel out there. But ar500 is not very hard at all and only it’s outer surface is hard. The core is soft (compared to martensitic steel like 52100 or ball bearings). Ar500 only has .3-.4% carbon, which is low carbon. It’s the .95% manganese and .75% chromium that gives it the boost. It is a very tough or strong steel. But isn’t very hard. This is of course in terms of actual hard steel. I’m not sure what his cone was made of but it wasn’t medium hard steel or hasn’t been heat treated correctly.
As an unqualified plumber, writer and experienced love maker, I appreciated the countdown to the epic moment. I fear a soiling of the pants, both front and rear would have occurred otherwise😂
It’s neat to see this. I watched a documentary that said war graves in the oceans are being robbed of their steel because steel made today have impurities from the A-bombs where steel made prior to it does not contain such materials making its scrap value much higher. In countries that lax regulations surrounding these graves have reported to have a huge spike in body parts being found in yards where scrap is being processed. Most are in bone form but hair and others have been found depending on where in the wreckage they were located.
I believe cooling the steel makes it stronger. Reducing the heat would also reduce the repulsive forces between its atoms, making it denser for a short period of time. It'd also counteract the heat produced during compression, allowing it to retain integrity for longer, since heat causes expansion and that expansion isn't uniform which wof lead to catastrophic failure. I'm not sure what steel it was but I think stainless steel gets stronger at cryogenic Temps. Idk,
just a little thing to note: metal quality varied greatly throughout WW-II, especially the T-34 went through many changes over time and location too as even the methods depended on what the factories had, by the end of the war T-34 armour was so low quality that some had cracks before even being fired upon.
When the disclaimer said “Do not attempt at home” it was really serious. I didn’t expect the armor to go all projectile on the entire lab. That was epic indeed!
100% knew this would be a disaster. At best the steel ball would go flying like a canon ball. At worst that slab of AR500 would essentially explode and probably damage the press. I was surprised how well the ball stayed put until realizing it was sitting on the indentation from the previous run. Regardless, that was pretty f'in awesome.
@@ralph3333 It's called cryogenic hardening which can greatly improve strength, hardness and wear resistance when used with certain steels. It will be more 'brittle' but a steel ball like that will be extremely strong in good condition. Now if the cryo-treated ball was hardened steel I believe it would have failed exactly as you imagined.
I mean, steady and continuous pressure will get through anything if there's enough of it, discounting material hardness of course. This doesn't accurately simulate things like bullets or artillery. Still cool though. Pressure welding that titanium at the beginning was pretty sweet.
@@user-bw6yp2ll9nwar is always madness. The technology looks cool but in the end it always makes people suffer. "Coolness" makes people blind. There must be a better way to be human.
That modern armour reminded me of a story my metal fab teacher told me. Someone he knew was asked to repair some part of a tank, but the nature of the material was secret, so he had to just guess a lot for working on it. After destroying a few tools and failing to cut the material with an acetylene torch, he finally to the military guys who had hired him that they'd have to disclosed what they could in order for him to work on the material. After taking the time to see what could be revealed, one of the first things the military guys asked was if the fabricator was wearing fully closed respiratory equipment and ventilation. Now, you should be doing that stuff in most cases anyway, but when working with normal steel it's not a big issue. After hearing this the fabricator said "I sure am now!"
@@vincasvosylius6045even just manganese steel fumes can be pretty damn nasty, you can get away without wearing a respirator for most materials, especially with good ventilation but any kind of armor plate is probably going to have chromium, vanadium, manganese, etc that you really don’t want to inhale
Truly Impressive Test on the hardness and resistance of materials... Too bad the damage to the equipment... with such an impact force there is really a risk of leaving your skin if you don't take the necessary precautions... Being in another room and also protected...😱🔥
The ending is a pitch perfect demonstration of how much energy goes into something like this. “Oh it’s just squeezing stuff”….naw man, the amount of potential energy in a demonstration like this is firmly in the “lethal” range. When several hundred tons of pressure finally equalizes (the armor breaks), it can send high speed, heavy shrapnel in any direction, doing the type of damage that would make a bullet jealous.
correct and the 500 refers to the ISO standard and is 500 Brinell Hardness , There is also 600 Brinell hardness available , called AR600 or QT600 , QT refers to "Quenched and Tempered"
WOW, just wow!! My husband welds with AR500, both at his previous job making oilfield trenches and at his new job making bumpers... Him and my brother in law always talked about this steel, I just never in my life figured it would be this strong!!
AR500 is Iron, Carbon, Manganese, Phosphorus (!), Sulfur, Silicon (ok this is not toxic), Chromium, Nickel, Molybdenum, Boron (!) I don't think it's very safe for handling, and simple steel should do better if you have a welding torch at hand. The same is with aluminum: nobody like to repair this (cars, ships, ...). Carbon is more nasty to repair.
@@losttownstreet3409 Phosphorous should not be more dangerous than Sulphur. It would likly only emit P2O5, wich is no more dangerous than SO3. In no way should working with a blowtorch create white Phosphorous (that would be toxic).
@@TheRealBatabii freezing metal to near 0 will cause it to harden like nothing else. it was literally to hard to break, soo the block of hardened steel broke first and very violently
I am a bit skeptical because T34 is known to have way too much hardened armor. Sure the projektile will not penetrate but it was prone to crack. But worst of all on shell impact it absorb all the energy transfer it to the other side creating splatter of hot almost molten sharp shrapnel scattering inside the thank. So even thou it seemingly survived direct impact without visible damage the inside situation may not be so optimistic.
Metallurgy and heat treatment has improved by a lot since 1930, but a t-34 is the worst example to list for WW2, the steel was of a very poor quality even by the standards of the 1940s. Like the other guy said, it was radically treated for hardness, which made spalling common every time it was hit by a larger shell, and it happened a lot because it was only 45mm thick. Because the armour was highly sloped, there was little space inside for 4 grown men, so there was a lot of meat for loose metal to shred into.
@@portnuefflyerhonestly some of our strongest to be produced from the Industrial age so far They have presses that do many times more than the 350 tons of pressure in the video
AR500 seems to be primarily used in body armour. It's probably not too different from the exterior layer of tank armour, but most of those are still classified. But the main protection of the front and parts of the side of tank armour only uses this for the surface layer, behind which is a number of composite layers. Tank designers often estimate the frontal protection of tanks in tons/m², while the thickness of front armour tends to be around 1 m (3.3 ft)
I feel like you're lucky to be alive after this one. Not sure how physically close you were when it went off but damn when that steel popped it treated your protective barrier almost like it wasn't there.
I wish the pressure gauge was displayed in each of the examples. Regardless, these are always interesting videos and the effort required to create them is appreciated.
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. And terrorists (puppets of the Antichrist) who misinterpret verses, out of ignorance and political motivations, and take them out of historical context (just like radical atheists do by the way), don't help either. Thank you very much for your time. Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures. Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement. It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them. (19-22 / Translated by Muhammad Asad).. Salam (Peace) -----------

Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures. Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement. It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them. (19-22 / Translated by Muhammad Asad).. Salam (Peace) -----------
I work with abrasion resistant steel (known as "AR steel"). It is quenched and tempered to give it hardness. A common brand name is Bisalloy. I'm not sure if it's the same thing as in the video. We have recently had issues with the steel plates failing violently while being bent. They're not as brittle as harder products such as cast iron or ceramics, but they're a lot less ductile than mild steel. So as in the video, if a 500-hardness steel (usually measured on the Brinell scale) is deformed too much it will fracture and fail catastrophically.
Dude, I am beyond impressed.I am a fully trained union Millwright who has studied metal my whole life of 61 years, and I had no idea that would happen, the liquified gas made the steel that hard?
Technically it's far more then you think. You maybe heard of the famous formular E=mc², it's for calculating how much energy mass contains. And for example: The mass of a person with a weight of 65kg (~143 pounds) contains the same energy as approx. 100.000 Hiroshima Bombs. No joke. Mass contains extreme amounts of Energy. We are just not yet able to "use" it properly.
@@ryanbayne1033 We allready do with nuclear power plants or fusion power. But you maybe want to know, why we can't just put a box of meat into an oven and turn the theoretical massive energy amount it contains into pure usable energy, right? It's very complex to answer this, but to describe it simply: Because there are 1. Different kinds of energy (kinetic energy, heat energy,.. ) and the big problem is the actual conversion from mass to energy or energy to mass. The Formula E=mc² actually just tells us how much energy mass contains, if we would be able to convert it 1:1 into energy. And that's technically impossible. By convert energy, you always have a loss and often you have to spend some energy first, before getting some. Also how to catch/store the energy? Think of an atomic bomb: By splitting atoms, enormous amounts of energy are released, which spread explosively in fractions of a second through enormous heat and force. If we were able to capture all of this energy without wasting any of it, nuclear fission would be an incredible source of energy. But we can't do that, not yet. We have nuclear power plants that do what an atomic bomb does under controlled conditions on a very small scale. But itself poses enormous risks and dangers. Perhaps at some point in the distant future we will find a way to better capture, use and transmit energy from conversion.
@@killgaet6253 yes, but there is an entire industry around reclaiming this steel...and once it is gone, that's it, we cannot reproduce it. That's all I'm pointing out.
Has anyone considered the following: The super cooled metal ball was placed on top of the room temperature AR500 sample. This caused the AR500 to cool rapidly at the point of contact. As the pressure increased, the metal under the ball continued too cool, and reached the transition temperature between ductile and brittle fracture. The cooled area suffered brittle fracture, which then carried through the AR500 causing it to "explode". The dull appearance of the fractured faces are characteristic of Brittle Fracture
With that much force? It was well beyond the transition temperature and probably was hot to the touch. All that energy has to go somewhere, so before it breaks it goes to heat. Once it breaks, it rapidly converts to kinetic, creating an explosion of sorts.
Not buying it. * The sphere had 20 minutes of total immersion in liquid nitrogen for the ball to fully reach temperature. This whole thing was done in less than 2 minutes. * The AR500 was not submerged in the liquid at all and it had much more mass than the ball. * Because it was a sphere there was a very little surface-to-surface contact area between the AR500 and the sphere. * The AR500 had full surface contact with the base below it making the mass of AR500 even more. * There are ungodly high temperatures being created with that kind of pressure further working against any temperature transfer.
I believe that your analysis is the best explanation. That the difference in temperature of the AR500 is what shattered it. I would have thought the frozen steel ball would have shattered first though.....like a rose dipped in liquid nitrogen.
If nobody got hurt it did it's job. The safety shit is for people, you can put the camera wherever you want if the content is good like this you just go buy another lense
Wow, that "epic moment" really was epic! I've never seen things blown off with such power in other tests. It's amazing to think the engine power that those tanks must have to be able to carry those tons of metal around.
Crazy. Definitely more a test of how hard the cones were compared to steel used in military armour, but also a great example of the balance that is struck between hardness and shattering. This is why modern armour has multiple layers to diffuse the impact energy both in shattering (e.g. one component reactive armour) as well as absorption to spread and absorb the energy over a greater area.
There's also a difference in shells, bullets, and other projectiles compared to this press. I'd wager a guess that a tank shell could defeat a lot of things shown that the press couldn't because of the energy and material difference. Typically the best way to defeat armor is to have something really dense that's moving very quickly.
@@nootnewtyour correct, the way to defeat armor is with speed, and density resulting in a larger force defeating the armor, which is why AP rounds are usually made out of depleted uranium and tungsten for its density. Combined with the shape of modern ammunition being like a dart allowing for more penetration as it’s more force in a smaller area
I’m sure the creator knows this but if you ever work with titanium be extremely careful. Titanium really likes to catch fire when it’s small enough and it’s almost impossible to put out.
The greatest fear of tank drivers everywhere is that someone is going to sneak up to a tank, setup a hydraulic press, and slowly penetrate the armor.
😂😂😂
Literally nothing they could do 😢
You'd be surprised how often it happens.
That's how we defeated the nazis. Didn't you hear? 😂

I love the "Do not repeat at home" warning, as though we're all going to pull out our hydraulic presses and punch holes through all the spare titanium armor plates we have lying around.
Wdym, just finished up picking up the pieces of glass that my shard of metal broke when it hit the neighbors window. I also fucked up my hydraulic press. 🤷♂️🤷♂️🤷♂️
No worries here as mine can't make that much force. It's made for lighter softer stuff.
Yup well they have to better be safe then be sorry and get sued & someone getting injured or worse killed u see how many safety procautions they took around the press just imagine if their was none.
Well, they had to get more careful after that incident with the documentary about the Manhattan Project.

As far as I know, tank armor in ww2 was tempered to be soft to absorb the energy a bit. Tempering to too hard would make the armor brittle. I could see hard armor like this working well as a skin on top of softer steel...Im sure the modern engineers have worked all this out...
That's kind of the way battleship armor such as Class A face hardened steel is designed, it's also always backed by a softer steel splinter protection layer to catch any spalling
I would like to see some krup steel from ww2
The armor of the T-34 that was used was actually a bit hard and you will see a lot of knocked out T-34s with large cracks in them from getting hit.
This video provides a critical example of the importance of making sure that your protective measures can stand up to sudden fractures or shatters at the upper end of the scale of the forces being used for testing.
And hearing protection, too!
Nice and interresting video 👍 However, it was a bit ironic that chipboard plates were used as protection when testing state of the art armour to destruction 🤔
Say you don't know how modern armor works without saying it. Modern armor is designed to be reactive and provide a counter concussion to absorb.
@@halvarmc671 Uh, think you responded to the wrong comment. Not sure this has anything to do with the video being an example for the importance of protective safety measures.

@@ctvaughan6623
Did he use a modern tungsten or uranium sabot equivalent tho? Nope, homogenous rolled toilet paper barely counts as armor since 90's.
Depleted uranium is a Weapon
All of this makes you actually frigthened of the things that these armors stand against. After all, the armor of WW2 was already tough and that was already difficult to deal with. But the modern one that survived a lot more punishment makes you actually impressed about what modern anitarmor weapons can actually DO.
Do not forget that the majority of modern tank armor uses higher quality alloys than what was shown here, and also usually is layered with some form of composite (usually advanced ceramics or in the case of the abrams, spent uranium-derived materials) that works in conjunction with the high end alloys to slow, catch, and disperse the energy of, modern super high velocity anti-tank rounds, as well as handle the heat jets from modern shaped charges. A T-90M, Abrams of any model, or a Leopard 2 of any model would simply sneer at any cannon or AP round that WWII could feasibly throw at them.
@@willkenny5687 "A T-90M, Abrams of any model, or a Leopard 2 of any model would simply sneer at any cannon or AP round that WWII could feasibly throw at them."
From the front? Most definitely. From the sides? Then I would be a bit concerned. From the back or top? They're a goner. Even ww1 artillery would go though the roof of a modern tank like a hot knife through butter.
Also, your tank list is weird, why list the T-90M, which is a top of the line tank, along with any model of Abrams and Leopard 2? An original Abrams or Leopard 2 is no where close to a T-90M, they are more like a T-72B but with a much worse gun in the case of the Abrams who originally only mounted the near obsolete L7 105mm riffled gun. The soviets where way ahead when it comes to guns as they already moved to a 115mm smoothbore gun back in the 60s when they made the T-62. Even the latest version of Abrams would probably be at a disadvantage against the T-90M as the Abrams tank has bigger weakpoint in the upper glacis. In a hull down fight, it's anyone's guess who has the better chance of penning the other since both armor compositions are unknown to the public at this point.
It would be very interesting to see WW2 naval armor
@@willkenny5687
Тут дело не только в качестве. Похоже сам подход к созданию броневой стали изменился.
Раньше считалось, что броня должна обладать высокой вязкостью чтобы снаряд застревал в такой броне примерно как палец в пластилине а сама броня при этом бы не разлеталась на кусочки как во втором случае (чтобы экипаж танка от осколков не пострадал).
Сейчас же, похоже, опять пришли к высокой твердости брони дабы броня сама по себе сопротивлялась какому-либо внедрению твердого материала (сердечника снаряда) а осколки в случае разрушения, видимо, должен удерживать противоосколочный подбой или какой-то хитрый слой брони из композитного материала.
@@skitidet4302 The latest version of the abrams at a disadvantage against a T-90M? Don’t make me laugh. The M1a1 abrams handled T72s using the same 2a46m main gun as the t90m in iraq, and was never penetrated. I have strong doubts that that situation has changed dramatically enough to put the M1a2sepv3 at substantial risk.
The soviets in the 50’s absolutely were leading the way by a lot when it came to tank technology, and the IS-3 was definitely better than anything the allies or axis had at the time, but materials technology has come a long way since then, I have very strong doubts that even its 122mm gun with WWII era ammo could take out a modern mbt.
And the reason as to why I included all of those tanks together is because the original M1, the original leopard 2s, and the T90M, all use technology from the 80’s and 90’s, and are thus roughly contemporary if not equivalent.
By far an EPIC moment indeed, OH MY GOD lol that was amazing. Thank you for sharing!
wrggg
6:17 there's no practical application for something like this which makes it so awesome. Great demonstration in material hardness
Fun fact: Old style AP shells weren't actually 'pointed'. They were very much like truncated, shouldered cones. It allowed the shell to penetrate, while alleviating a good bit of the weakness of an acutely angled point. The classical 'bullet' shape was actually just a cap that served to increase the ballistic coefficient and to crush as the projectile made contact to help support the shell so it didn't shatter on impact.
The naval dude Drachifell ! has a good episode on shells vs armor.
also its the inside of the AP round that did the job, meaning tungsten carbide and explosive detonation based on tests so that once inside a tank it would exploded killing everyone and also disabling the tank as well?
Yep. Ballistic capped. Just there for the aerodynamics.
@@davidcox3076 spot on champ
I was really expecting that super-cooled ball to shatter way before the armor.... quite the opposite happened. If they could cool a projectiles tip like that, it would penetrate virtually any armor. heh
The problem with the first test is that spaced and layered armor is meant to bleed energy from the projectile to eliminate its penetration. A constant input of energy, like from the press, is always gonna crack it because that's not what it was meant to defeat
It looks like they made it to break perpendicular to the normal plane of the installed plate. It cracks perfectly horizontally and vertically. Very impressive.
the point of this video is to see how it does against hydraulic press
@@NekosaHaruna They only compare "yellow" and "warm" at the same time. The structure of steel is clearly different, while 1940 sends a big hello to 2010. Steel production is not drawing in office programs by "effective" managers.
Exactly, a true comparison, like apples to apples, would be a single piece of forged titanium the same size as the steel piece. This is grapes to apples.
Well then it's fucking shit lmao, armor doesn't get attacked once. If it can't handle a volley of bullets then it just isn't good.
RIP entire studio. That was a lot of pressure!
I've watched this so many times, it's practically my new happy place!
The way that steel blew up at the end was like a giant fragmentation grenade! Pretty scary stuff actually. Now I can see why all of the safety precautions are necessary. I’m very surprised by how much stronger our steel has gotten, I didn’t think there was this much room for improvement.
that's how the people on the titan sub died when the sub imploded that quickly
Part of the reason is because different steels are made for different purposes.
The Soviets could have made armor steel similar to AR500 back in the 1940's. in fact, some of their tank armors were even harder, but there's a reason they didn't continue doing this. Tank armor is not supposed to be as hard as possible. Steel is on a spectrum between hardness (ability to resist deformation) and toughness (ability to withstand shock). Too far in either direction would make it bad for the armor.
If tank armor was super hard, then it would also be super brittle, and big impacts (like incoming shells) would cause it to shatter super easily. Shards of razor-sharp metal would fly everywhere inside the tank and kill a lot of people.
@@raven4k998the pressure of the water was more deadly than that carbon fiber vessel. If that's what you meant, you'd be correct
@@raven4k998With the Titan they used carbon fiber, very strong but when it fails it fails suddenly instead of deforming and bending which could be the difference between getting back to the surface before total failure. I've also seen an example of this in motorcycle racing where a damaged rear wheel made of carbon fiber failed instantly and blew into pieces so they don't use those now haha
I think we have long ways to go not just alloy formulas but more like techniques of structural manipulations
To be honest, I thought and expected the super-cooled steel ball to shatter. I didn't expect what we saw. I'm glad I wasn't in that room.
Right, those armor chunks shot out with force. Bad day to be nearby
Maybe someone can explain why the ball survived after the dunk in liquid nitrogen. I'm willing to guess that the ball actually work-hardened for several millimeters deep, maybe an inch deep? Is this possible? So if the armor was equally work-hardened, it has a shape that was not as strong to withstand the pressure? Internally the armor did not represent an equally tall sphere, for one thing, but has more middle dimension. This has me stumped somewhat.
Think it has to do with the liquid nitrogen allowing energy to be conducted more efficiently through the ball to the metal block.
@@YouKnowTheyExistthere are 2 big reason why this happen. As someone else pointed out the energy was dispersed a lot more with the liquid nitrogen and the shape of the ball will also disperse energy a lot more than a cone, it will stay more on the surface of the ball meaning it wont damage it as much.
@hammerheadxray8152 I was expecting the same thing honestly. My guess as a metallurgist is that the plate already had some cracks initiated in it from the previous test while the ball did not have any stress concentrating flaws. Both materials are brittle given the brittle fracture surface left in the plate but because the plate may have started with more flaws it fractured first.
That near perfect 4 way split looked nuts in slow mo.
I'd like to see a colab between this guy and the slowmo guys!!! That would be insane!!!
That… Is sick! The armor fragmented and “exploded” just like a grenade with an insane power. I think this was the most dangerous press video I’ve seen so far. Great show
Hmmm...very dangerous!
Not going to think too much about it: definitely w Top 5!
This video is actually a great example of why tanks shouldn't have too sturdy armor; although this isn't a perfect example, seeing it shatter like that is similar to the phenomenon of 'spalling', which is when armour fractures instead of deforming, causing armour chunks on the inside to break loose, which is _extremely_ hazardous for the crew inside. During WWII the T-34 was notorious for this because they made it overly strong, and therefore brittle.
@@TheEDFLegacy So i guess they need a double layer of armor ? A very strong outer layer and a softer inner layer so that the inner layer stops the fragments of the shattering outer layer. Maybe even an armor plate with gradient hardness where the outside is super hard and it gradually softens to the inside would work ?
Oh well since nothing receives better funding than the army and weapons industies, im sure they have thought about that and tried everything :)
@@arjensmit6684 Yep, and this is one of the conventions you see with a lot of modern tanks. The M1 Abrams had depleted uranium as a dense shock absorber. The problem there is that they had to stop using that because of situations where uranium did the uranium thing and irradiated the crew, depleted or not. Other materials are still used, however.
@@TheEDFLegacy the T-34 armor here looked as if it was mild steel. These days tanks will use some lightweight kevlar spall liner.

@@vayalond7203 Yeah, diamond is incredibly abrasion resistant, kinda like the AR500 steel brick that exploded in the video, both are used for things like teeth on a bore drill since they just don't wear away quick at all. Diamond is a 98.07 HRC, while AR500 is among the highest steels at 48.3 HRC. 6061-T6 Aluminium is a 60 HRB, and doesn't have an HRC since its just not in the same category of hardness as steel alloys, for comparison an HRB of 82 rates an HRC of 1, or 120 HRB rates 55 HRC, its due to the different weight and from using a different surface, HRB is measured with a 100kg weight on a 1/16" ball while HRC is a 150kg through a diamond brale indenter. There are steels harder than AR500, even up to 68, but much higher than AR500 seems to be going into specialty alloys that are very difficult and expensive to manufacture. There is also CrCoNi, which rates 468 HV hardness, which is about 46 HRC, but it performed excellently from the looks of things at extremely low temperatures, on the order of a yield strength over 500 MPa under 100K, where a material like 2.25Cr-1Mo, or A387 Grade 22, yielded at about 370 MPa at 100K, 380 MPa at around 20K. Shit, I did it again, I rambled but I typed so much I don't want it to go to waste, so lol sorry for the word vomit XD
@@vayalond7203 They routinely cut diamonds with water as well as lasers.
I think you may have misunderstood the 'hold my beer' meme- it's supposed to represent when an overconfident person says 'hold my beer' and then quickly gets humiliated by who-or-whatever they had just underestimated.
The first example was an old Yosemite Sam cartoon where some yahoo is challenged by Sam and asks someone to 'Hold my beer.' before getting shot to pieces.
But, I agree with your intent re: the strength of steel- most people still think, for example, that titanium is both harder than all steels, and stronger, by mass (which it is not) in addition to by volume (which is may be). And, re: diamond... yeah... (hardness has little to do with tensile/compressive/elastic/plastic/etc strength). Cheers !
@@bholdr----0 Okay, learned something new today
Holy crap,I thought the metal ball would shatter after being in liquid Nitrogen,I didn't expect everything else around it to break instead(Including the camera!)😂
Same, very interesting.
Actually I was wondering whether his camera ever got broken due to these experiments. And the very next moment 💀✌️
Putting heat treated steel in liquid nitrogen adds even more hardness (even after it has warmed back up again) Applied Science has a good video on this. BBs are already made to be extremely hard, so I'm not surprised it wrecked the AR500 plate. Obviously brittleness comes into play with dynamic loading so you couldn't expect it to survive being used as a bullet, etc.
@@jhonbus ..it wouldnt work as a bullet... perhaps on a very short distance wher it does not experience much friction and heating... would be interesting to see someone test actually..from 10m to 1km or so...
..and yes just because its already heat threathened (has a martensite electron structure) ... the way electrons move in the material makes it extremely much harder when he electron states r being locked at lower temperatures... but it would be hard to keep a bullet below 80 Kelvin (below -193 deg C), of scientiffic curiousity one could possibly use liquid nitrogen for 20 mins and then use liquid Helium pressurized (-4 Kelvins), it probably wouldent be extremely hard to build a pressure cylinder to pressurize a container for this guys...
A SHARP WARNING!, LIQUID HELIUM IS VERY DANGEROUS TO PLAY AROUND WITH, IN IT LIQUID STATE IT CAN EXPAND (EXPLODE) WITH A FORCE GREATER THAN TNT!...
Ball bearings are made of 52100 steel. Around 1% carbon. They can be fairly hard. There’s more hardenable steel out there. But ar500 is not very hard at all and only it’s outer surface is hard. The core is soft (compared to martensitic steel like 52100 or ball bearings). Ar500 only has .3-.4% carbon, which is low carbon. It’s the .95% manganese and .75% chromium that gives it the boost. It is a very tough or strong steel. But isn’t very hard. This is of course in terms of actual hard steel. I’m not sure what his cone was made of but it wasn’t medium hard steel or hasn’t been heat treated correctly.
As an unqualified plumber, writer and experienced love maker, I appreciated the countdown to the epic moment.
I fear a soiling of the pants, both front and rear would have occurred otherwise😂
It’s neat to see this. I watched a documentary that said war graves in the oceans are being robbed of their steel because steel made today have impurities from the A-bombs where steel made prior to it does not contain such materials making its scrap value much higher. In countries that lax regulations surrounding these graves have reported to have a huge spike in body parts being found in yards where scrap is being processed. Most are in bone form but hair and others have been found depending on where in the wreckage they were located.
10 year old child: "Why don't we just make planes out of this?"
That’s what the MiG-29 wanted to do. But it was already a heavy load of crap with its powerful engines NEEDED to even get that thing of the ground.
In other word because steel is heavy as shit
They did, with the MiG-25. It's a piece of shit.
The blackbird made it work, all ironically from the Soviet titanium supply
Heavy
I was expecting the supercooled ball to be much brittle and explode easily when got in contact with the AR500. The outcome was unexpected.
same !!!
Right
@@JimmyR42v accurate
I believe cooling the steel makes it stronger. Reducing the heat would also reduce the repulsive forces between its atoms, making it denser for a short period of time. It'd also counteract the heat produced during compression, allowing it to retain integrity for longer, since heat causes expansion and that expansion isn't uniform which wof lead to catastrophic failure.
I'm not sure what steel it was but I think stainless steel gets stronger at cryogenic Temps. Idk,
The steel acts like a heat sink and start sucking the cold out of the ball bearing vary fast
just a little thing to note: metal quality varied greatly throughout WW-II, especially the T-34 went through many changes over time and location too as even the methods depended on what the factories had, by the end of the war T-34 armour was so low quality that some had cracks before even being fired upon.
When I worked in the steel industri we used AR for abrasive resistant steel and AM for armor steel.
When the disclaimer said “Do not attempt at home” it was really serious. I didn’t expect the armor to go all projectile on the entire lab. That was epic indeed!
Oh well, I guess I'll have to return all the hydraulic presses I just got for our family home
Can I have plz plz plz plz plz, I really want to destroy stuff
100% knew this would be a disaster. At best the steel ball would go flying like a canon ball. At worst that slab of AR500 would essentially explode and probably damage the press. I was surprised how well the ball stayed put until realizing it was sitting on the indentation from the previous run.
Regardless, that was pretty f'in awesome.
I was expecting the ball to be brittle n explode early on.
@@ralph3333 It's called cryogenic hardening which can greatly improve strength, hardness and wear resistance when used with certain steels. It will be more 'brittle' but a steel ball like that will be extremely strong in good condition.
Now if the cryo-treated ball was hardened steel I believe it would have failed exactly as you imagined.
First time I’ve seen something push back so thoroughly. The press is still undefeated though!
not on the modern armor
Could you say that you were imPRESSed?
Slow, progressive force isn't really like live munition situations though
The modern armour defeated it???
3:24
Awesome work. That wafer board safety barricade didn't stand a chance 😂 maybe later plywood with steel sheet
I mean, steady and continuous pressure will get through anything if there's enough of it, discounting material hardness of course. This doesn't accurately simulate things like bullets or artillery. Still cool though. Pressure welding that titanium at the beginning was pretty sweet.
First of all I hope youre alright and I'm sorry for your destroyed equipment. Secondly THIS IS EXACTLY THE CONTENT WE WANT.

That modern armour reminded me of a story my metal fab teacher told me. Someone he knew was asked to repair some part of a tank, but the nature of the material was secret, so he had to just guess a lot for working on it. After destroying a few tools and failing to cut the material with an acetylene torch, he finally to the military guys who had hired him that they'd have to disclosed what they could in order for him to work on the material. After taking the time to see what could be revealed, one of the first things the military guys asked was if the fabricator was wearing fully closed respiratory equipment and ventilation. Now, you should be doing that stuff in most cases anyway, but when working with normal steel it's not a big issue. After hearing this the fabricator said "I sure am now!"
depleted uranium?
@@vincasvosylius6045even just manganese steel fumes can be pretty damn nasty, you can get away without wearing a respirator for most materials, especially with good ventilation but any kind of armor plate is probably going to have chromium, vanadium, manganese, etc that you really don’t want to inhale
@@vincasvosylius6045thats for ammo not armor
@@affegpus4195 many modern tanks use depleted uranium plates on top of their standard armor. It’s incredibly dense and helps with sabot rounds.
Beryllium
Truly Impressive Test on the hardness and resistance of materials... Too bad the damage to the equipment... with such an impact force there is really a risk of leaving your skin if you don't take the necessary precautions... Being in another room and also protected...😱🔥
You only need a single fullstop to separate sentences.* Those multiple fullstops serve no purpose other than making reading more difficult.*
dude from the bottom of my heart thank you for this lol sorry for your loss i know the video probably doesnt offset the cost
AR500 is typically used in abrasion resistant application like feeder bins for asphalt. Very hard stuff but also incredibly brittle
and body amour
Thats why we back the armor up with a splinter shield made of softer steel.
At least the Navy did... can't talk about tanks.
It also work hardens while cutting...
Tank armor does not want armor that is brittle. A single impact could make the armor shatter or weaken to the point of breaking
Yes very brittle, it fractures only at 350 tons.
The ending is a pitch perfect demonstration of how much energy goes into something like this. “Oh it’s just squeezing stuff”….naw man, the amount of potential energy in a demonstration like this is firmly in the “lethal” range. When several hundred tons of pressure finally equalizes (the armor breaks), it can send high speed, heavy shrapnel in any direction, doing the type of damage that would make a bullet jealous.
It would be fun to see a modern depleted uranium or tungsten projectile being pressed into the 1940 armour and the 2010 armour.
Like comparing tin to modern day steel alloys, I could very much imagine all of this, fascinating to see it play out though.
The AR stands for 'Abrasion Resistant', it's not just for armor but used anywhere in industry where it needs to be resistant to abrasion.
Thanks for sharing.
Automatic Rifle
Armour Republic
It stands for Assault Rifle!!!
correct and the 500 refers to the ISO standard and is 500 Brinell Hardness , There is also 600 Brinell hardness available , called AR600 or QT600 , QT refers to "Quenched and Tempered"
WOW, just wow!!
My husband welds with AR500, both at his previous job making oilfield trenches and at his new job making bumpers... Him and my brother in law always talked about this steel, I just never in my life figured it would be this strong!!
AR500 is Iron, Carbon, Manganese, Phosphorus (!), Sulfur, Silicon (ok this is not toxic), Chromium, Nickel, Molybdenum, Boron (!)
I don't think it's very safe for handling, and simple steel should do better if you have a welding torch at hand.
The same is with aluminum: nobody like to repair this (cars, ships, ...). Carbon is more nasty to repair.
@@losttownstreet3409 Phosphorous should not be more dangerous than Sulphur. It would likly only emit P2O5, wich is no more dangerous than SO3. In no way should working with a blowtorch create white Phosphorous (that would be toxic).
haha i love the utter chaos with the explosion
Perfect (probably unintented) modern day demonstration of how so many perished from flying shrapnel
That “epic moment” was an understatement! That was way more “epic” than I was expecting.
I actually thought the ball would explode as it had been frozen in LN
@@petenikolic5244yeah I thought freezing would make the ball weaker not stronger
@@TheRealBatabii freezing metal to near 0 will cause it to harden like nothing else. it was literally to hard to break, soo the block of hardened steel broke first and very violently
Absolutely INCREDIBLE!!! I had no idea that modern armor plates were this hard/strong!? That was an awesome vid, thank you for sharing.
I am a bit skeptical because T34 is known to have way too much hardened armor. Sure the projektile will not penetrate but it was prone to crack. But worst of all on shell impact it absorb all the energy transfer it to the other side creating splatter of hot almost molten sharp shrapnel scattering inside the thank. So even thou it seemingly survived direct impact without visible damage the inside situation may not be so optimistic.
Metallurgy and heat treatment has improved by a lot since 1930, but a t-34 is the worst example to list for WW2, the steel was of a very poor quality even by the standards of the 1940s.
Like the other guy said, it was radically treated for hardness, which made spalling common every time it was hit by a larger shell, and it happened a lot because it was only 45mm thick. Because the armour was highly sloped, there was little space inside for 4 grown men, so there was a lot of meat for loose metal to shred into.
Rifle plates can stop any Small arms bullet except maybe a 50 bmg. They are strong af. I have some armor plates myself.
It makes one wonder, how bad ass are the tool used to work that armor?!
@@portnuefflyerhonestly some of our strongest to be produced from the Industrial age so far
They have presses that do many times more than the 350 tons of pressure in the video
AR500 seems to be primarily used in body armour. It's probably not too different from the exterior layer of tank armour, but most of those are still classified.
But the main protection of the front and parts of the side of tank armour only uses this for the surface layer, behind which is a number of composite layers. Tank designers often estimate the frontal protection of tanks in tons/m², while the thickness of front armour tends to be around 1 m (3.3 ft)
I feel like you're lucky to be alive after this one. Not sure how physically close you were when it went off but damn when that steel popped it treated your protective barrier almost like it wasn't there.
I wish the pressure gauge was displayed in each of the examples. Regardless, these are always interesting videos and the effort required to create them is appreciated.
Also it looks that the pressing cone is not the same.. A shame
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. And terrorists (puppets of the Antichrist) who misinterpret verses, out of ignorance and political motivations, and take them out of historical context (just like radical atheists do by the way), don't help either. Thank you very much for your time.
Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them).
Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI).
Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy.
Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful.
Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI).
Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad).
Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning!
Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures.
Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement.
It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them.

To get technical, this was a display of its strength, not toughness. Had it been tougher, it wouldn't have exploded.
Это плака о двух концах, броня должна быть не только прочной но и пластичной, чего не сказать об ar500
Sketchy Russian comment…
I work with abrasion resistant steel (known as "AR steel"). It is quenched and tempered to give it hardness. A common brand name is Bisalloy. I'm not sure if it's the same thing as in the video.
We have recently had issues with the steel plates failing violently while being bent. They're not as brittle as harder products such as cast iron or ceramics, but they're a lot less ductile than mild steel. So as in the video, if a 500-hardness steel (usually measured on the Brinell scale) is deformed too much it will fracture and fail catastrophically.
Dude, I am beyond impressed.I am a fully trained union Millwright who has studied metal my whole life of 61 years, and I had no idea that would happen, the liquified gas made the steel that hard?
Wow, now that was interesting, that ball bearing caused that plate to explode like a hand grenade!
That detonation of a solid piece of steel goes to show how much energy a solid object can hold! Impressive!
The difference between strong and hard metals (you'd be surprised how many people think it's the same thing)
Technically it's far more then you think. You maybe heard of the famous formular E=mc², it's for calculating how much energy mass contains. And for example: The mass of a person with a weight of 65kg (~143 pounds) contains the same energy as approx. 100.000 Hiroshima Bombs. No joke. Mass contains extreme amounts of Energy. We are just not yet able to "use" it properly.
@@benfordrin6978 Well, when we do I hope its for something everyone wants. 24/365 Mc Ribs...
How can we not use this to generate power?
@@ryanbayne1033 We allready do with nuclear power plants or fusion power. But you maybe want to know, why we can't just put a box of meat into an oven and turn the theoretical massive energy amount it contains into pure usable energy, right?
It's very complex to answer this, but to describe it simply: Because there are 1. Different kinds of energy (kinetic energy, heat energy,.. ) and the big problem is the actual conversion from mass to energy or energy to mass.
The Formula E=mc² actually just tells us how much energy mass contains, if we would be able to convert it 1:1 into energy. And that's technically impossible. By convert energy, you always have a loss and often you have to spend some energy first, before getting some. Also how to catch/store the energy?
Think of an atomic bomb: By splitting atoms, enormous amounts of energy are released, which spread explosively in fractions of a second through enormous heat and force. If we were able to capture all of this energy without wasting any of it, nuclear fission would be an incredible source of energy. But we can't do that, not yet. We have nuclear power plants that do what an atomic bomb does under controlled conditions on a very small scale. But itself poses enormous risks and dangers.
Perhaps at some point in the distant future we will find a way to better capture, use and transmit energy from conversion.

if it was kruppstahl of the Tiger Ausf. B Tiger II or something similar well that would have been painful to see but a simple T-34 thats nothing.
This was really good!
This is literally a case of unstoppable force meeting an unmovable object. Very interesting
Was NOT expecting that!! Was waiting for the ball bearing to 'splode...but the armor did instead?? Fascinating!! 😁👍
Has anyone considered the following:
The super cooled metal ball was placed on top of the room temperature AR500 sample. This caused the AR500 to cool rapidly at the point of contact.
As the pressure increased, the metal under the ball continued too cool, and reached the transition temperature between ductile and brittle fracture.
The cooled area suffered brittle fracture, which then carried through the AR500 causing it to "explode".
The dull appearance of the fractured faces are characteristic of Brittle Fracture
With that much force? It was well beyond the transition temperature and probably was hot to the touch. All that energy has to go somewhere, so before it breaks it goes to heat. Once it breaks, it rapidly converts to kinetic, creating an explosion of sorts.
So your saying we need to super cool our rounds and make them steel then infantry can shoot through tank armor?
@@jeffbotelho5035 Im not sure what super cooled rounds will do to the firing mechanism and barrel. :F
Not buying it.
* The sphere had 20 minutes of total immersion in liquid nitrogen for the ball to fully reach temperature. This whole thing was done in less than 2 minutes.
* The AR500 was not submerged in the liquid at all and it had much more mass than the ball.
* Because it was a sphere there was a very little surface-to-surface contact area between the AR500 and the sphere.
* The AR500 had full surface contact with the base below it making the mass of AR500 even more.
* There are ungodly high temperatures being created with that kind of pressure further working against any temperature transfer.
I believe that your analysis is the best explanation. That the difference in temperature of the AR500 is what shattered it. I would have thought the frozen steel ball would have shattered first though.....like a rose dipped in liquid nitrogen.
I would love to see this in real time of an actual shell at this range
Very impressive !
I love how he still hasn't managed a barrier setup robust enough to keep his gear from getting damaged lol
Imagine setting up a wood barrier and thinking it'll be enough...
get a bit of gratitude pal
dude shits moving like 400 mph and weighs like 4 pounds. make a wall that can survive that 20 times
If nobody got hurt it did it's job. The safety shit is for people, you can put the camera wherever you want if the content is good like this you just go buy another lense
He clearly need a new barrier made of AR500
That was truly epic! The amount of energy released is incredible.thank you for sharing this content.
Must take a lot of electricity to build up that energy too.
Das One Crazy Mo Fo
a reminder of why this is very dangerous
That looked like a much more expensive test than you expected.
That one chipboard piece that survived completely untouched is a Jedi.
"Don't do this at home" yeah, as if we've all got insanely powerful hydraulic presses and plates of titanium just hanging out in our garages
my titanium plate makes for a very nice pillow
don't you?
D-Do you not?
Peasant.
speak for yourself
Wow, that "epic moment" really was epic! I've never seen things blown off with such power in other tests. It's amazing to think the engine power that those tanks must have to be able to carry those tons of metal around.
It's less the weight and more the composition of it. But yes, accurate.
That's nothing
Right?! I've seen alot of "epic moments" that left much to be desired but this I feel was an understatement!
@@blake9358bc u see these things daily right?
amazing!!!!!!!! the lat one breaks the armor like a bomb!!!! so much energy liberated!!!!
That steel breaking caused an earthquake as powerful as when caseoh jumps
Crazy. Definitely more a test of how hard the cones were compared to steel used in military armour, but also a great example of the balance that is struck between hardness and shattering. This is why modern armour has multiple layers to diffuse the impact energy both in shattering (e.g. one component reactive armour) as well as absorption to spread and absorb the energy over a greater area.
There's also a difference in shells, bullets, and other projectiles compared to this press. I'd wager a guess that a tank shell could defeat a lot of things shown that the press couldn't because of the energy and material difference. Typically the best way to defeat armor is to have something really dense that's moving very quickly.
@@nootnewtyour correct, the way to defeat armor is with speed, and density resulting in a larger force defeating the armor, which is why AP rounds are usually made out of depleted uranium and tungsten for its density. Combined with the shape of modern ammunition being like a dart allowing for more penetration as it’s more force in a smaller area
I’m sure the creator knows this but if you ever work with titanium be extremely careful. Titanium really likes to catch fire when it’s small enough and it’s almost impossible to put out.
Yo that thing looked like a thermite explosion, crazy
Crazy anime magic, perfect 4-way split, and crazy damage. DC comics needs to learn from this.
What a pleasure to see a pure manly video 100%.
