Thanks for the video. It was very interesting. I'd like to add that the Humans discovered "wrought Iron" thousands of years ago, which has more than 2,4% Carbon in its alloy with Iron. The best alloys at that time were roughly able to get down to 4,5-5% Carbon. Usually they had a higher carbon concentration and were brittle, easy to break and a lot more susceptible to corrosion. By finding a method to deprive the wrought Iron of Carbon, down to an area of 0.02- 2,4 % carbon in the alloy, we were able to produce what we now know as "Steel". Which we now know for a few hundred years.
Sandvik 14C28N is a stainless steel with the following composition: - Carbon (C): 0.62% - Chromium (Cr): 14.00% - Manganese (Mn): 0.60% - Silicon (Si): 0.40% - Phosphorus (P): 0.025% - Sulfur (S): 0.010% - Nitrogen (N): 0.11% This composition gives 14C28N its excellent combination of hardness, corrosion resistance, and edge retention, making it a popular choice for knife blades.
Most of my newer machines are made of the poorest quality steel that corrode away, while my dads and grandfathers are still sound. Progress and greed. 😢
The amount of old steel being found and scrapped way outnumbers recycled steel. These material censuses are falsely projected. Recycling is a joke of what it's supposed to be.
I imagine that you also can't control what properties recycled steel would have, unlike newly manufactured steel. There are some applications where you really need that level of property control.
That ratio isnt correct, because recycled metal is far, far weaker than ore steel. The application the steel is used for determines what will be used. And that is constantly changing.
Yes But if 1/3 of annual steel production is reliant upon scrap...essentially every 3 years that needs to be "RE-Recycled"...Which Is Completly Impossible & Unsustainable...Even WithOut Any Future Increases on Steel Demand. It'll be Decades to a Century+ for the Steel used in a new Skyscraper to even have the opportunity to be scrapped!Even Worse; he says "About Half of All Steel EVENTUALY Gets Melted Down/ RE-Used/Scrapped~Meaning that around 50% of Steel IS LOST & DOES NOT GET RECYCLED (Much of it Rusting away to Dust;Even if "Rustproof",much more will be Lost to the Landfills & Oceans,Or left discarded & forgotten to be Burried within the Sands & Earth from which it came.
Then, by the"laws"of supply & demand (as well as those of "inflation") Why is it that while we are constantly being told that "Inflation" is the cause for the Cost$ of nearly Everything exploding sky high, & thus within only the last few years the $$$'s of Buying New Steel Have Literally Multiplied, while the Costs of New (12v "Car")-Batteries have approx. DOUBLED!! to around $200+!!! ALL THIS; MEANWHILE; The PriceRate$ PAID TOO Scrappers/Recyclers for; ScrapMetal/Junk-Cars/etc/& USED Car BATTERIES; HAVE ACTUALLY GONE DOWN!!

Seems like Price Fixing is the only logical explanation...BUT! ONLY ON the (Artificially-Bargain Priced)RATES THEY'RE PAYING FOR SCRAP....WHILE THEY then MAKE RECORD HIGH PROFITS by JACKING UP THEIR PRICES TO THE CONSUMER'S - SKY HIGH..."..Beacuse...ummm...INFLATION...yeah thats it..."
Material engineering makes my mouth drool
Just like those balls
Same
I love steel❤
Pittsburgh pa?
Scrap steel is mystery steel. Can have all kinds of additions instead of making specific steel from scratch.

Was gonna post this but you beat me to it : )
Thank you. I knew they weren't right when they said that.
I have 4 generations that worked in the same steel plant. It may be in my DNA 😂
Ditto… same here. Such an important piece of American history, but glad to be part of it. So sad to see our mill go.🥹
How do I join this party?
“What’s your car made of?” “Cars”
😂…you’re not wrong. 🙂
👍 Wonderful information you have shared. Thank you.
Should have never closed the Bethlehem Steel plant.
Sandvik 14c28n is my favorite steel, not sure the generic name but that's the brand.
Sandvik 14C28N is a stainless steel with the following composition:
- Carbon (C): 0.62%
- Chromium (Cr): 14.00%
- Manganese (Mn): 0.60%
- Silicon (Si): 0.40%
- Phosphorus (P): 0.025%
- Sulfur (S): 0.010%
- Nitrogen (N): 0.11%
This composition gives 14C28N its excellent combination of hardness, corrosion resistance, and edge retention, making it a popular choice for knife blades.
That ball bearing ahit is dope

Aaaaahaaa nice video 👌👌👌👌❤️❤️
OMG very nice ❤❤❤❤

You mean that more can be done?
ohhhh 😮😮😮
I heard that Iron working was started in Armenia during Iron ages or so.
Basically long time ago.

This is a great video I just wish you would have added in aluminum aluminum is one of the most used Metals in the world also one of the most recycled
Because we sink ships rather than scrapping them.
Thousands of years ago?
From it's mom and dad
Were those balls
Early steel was more of an accident than an invention
Why is the video titled "Behind-the-Scenes"? It doesn't really fit with the content...
You cannot use 100% recycled steel and still get high quality high strength steel
Okay but do you always need that?
British Steel is the best type of steel in the world.
Hi where is British Isles is good steel..sorry for you ,,caz all ferniz uk country dose,t work u tell people this good u must be respected men
@@shahababadsafian5838bahahaahahajha!!!!😂😂😂SOOOO TRUE-STORY!! My friend!
Those are my balls of steel 😂
The word you are struggling for. Is GRADE... GRADES OF STEEL
Queria que estivesse em português para que eu possa entender o que vc fala
I watched other video saying steel is hardest to recycle.
Pretty confusing world!
The uk are going to be going out of new steel production 😢
Barely any plastic is recycled it’s mostly so much corporate propaganda that makes us think it is.
Invented? You mean discovered. 😂
That ratio isnt correct, because recycled metal is far, far weaker than ore steel. The application the steel is used for determines what will be used. And that is constantly changing.
So basically some machine shits it out?
Hav we stopped selling it to China for super cheap yet?
it doesn't tell you or miss lead you you that you have to use ore when you recycle it d a given, to much for me to get into here.
New bridges won’t become scrap again for a long time - True. But old ones will

Steel was made 350million years ago and was better.😂😂😂 truth hurts
Plastic cant be recycled
