Rebar is made from scrap steel. There is no heat treating. It is not forged. It is a low carbon flexible steel made from scrap. To make a quality hammer, the steel should be: high carbon, heat treated and then forged.
You don't want to use high carbon steel for hammers. You want medium carbon or mild steel depending on the hammer. Some hammers are made out of bronze, brass copper and even lead. A fully hardened high carbon hammer is unsafe to use. The more you use it the harder it gets from workhardening. Eventually it will get so hard it will become brittle and shoot shards of hardened metal off into your body. Lastly You don't heat treat before you forge. That would be totally pointless. You heat treat after the forging.
Most Rebar is not made from scrap. It has a highly calculated specification for it's mechanical properties to be used by engineers and codes and inspectors. Most rebar is heat treated. You think the bridges skyscrapers and parking structures are just are thrown together with random materials melted down from costum jewelry? Rebar is indeed forged there is no otherway to make it. You think they cast a 1/2 inch thick piece of steel that is 50 foot long? Rebar is forged through dozens of dies and rollers. Some rebar is manufactured by reclaimed steel, such as ship anchor chain, steel rail and ship hull plate. Those types of steel are reforged into rebar. It is mostly allowed to slowly cool down so its in a semi annealed state meaning it isn't hardened so it retains more flexibility. It isn't scrap. Its used for less demanding concrete work. For small buildings projects.
You can double your production speed if the second forging dropped to the far guy. He could load the second run while the first guy feeds a new one at the same time.
Every hammer is made using a hammer. There is an unbroken line of hammers dating back to when the first human beat metal into submission with a rock, the first hammer.
it must be so comfortable to work with sandals on. 5:29. every one of these videos show how these people have to work in unsafe environments to feed themselves and their families. no insurance, no retirement, just a life of trying not to get hurt/maimed every day. pitiful. in the u.s the end of the line for junk steel like this IS rebar.
You’d think they’d use a simple carbon steel rod with added manganese and silicon, say about 1/2 % carbon, 1.5% manganese, 1/2 % silicon, then “oil quench” at the end of the forging cycle, followed by a draw warm enough for long enough to bake the oil residue into a blackish finish for the metal. (Small amount of linseed oil added to the quench bath, that or a separate dip after quenching) This is a relatively *cheap* alloy steel, by the way - a lower-carbon version of 9260 steel. The result would be very tough and wear-resistant. This would give a *substantially* better hammer head at *minimal* added cost and effort.
A lot of the choices and decisions of metal stock is whats available locally there. I don't know what steel is shown in this particular video but Some places make rebar from plate from local ship breaking outfits. They take the plates off with oxygen Lance torches at the beach then take the steel plates inland and shear off sections heatit up and send through a rolling mill with a bunch of dies and finish with rebar dies. So yeah ideally a great alloy it may be for hammers
Rebar is probably the cheapest grade of steel available. There is no blending of steels to get a certain characteristic or sampling of raw material to arrive at a desired end result. You have hammer heads that may split from being brittle or peen outward from being too soft.
This is not true. Most rebar is used in bridges skyscrapers and dams. Its highly controlled and made to very specific specifications made by engineers and codes.
@@honkie247 just because they dont mention what material is being used in the video... you assume its the wrong type. Very few videos on CZcams have any mention of material type.. they gloss over that information. Did they say in the description what kind of electricity was being used.. do you think that is incorrect as well. I can see this rebar has a stamp in it. I can't read it but that stamp has the relevant information such as alloy type and size. Also this isn't being made into bearing for a hypersonic jet engine. Its a claw hammer.. even the worst grade of Rebar is suitable steel for a claw hammer. If the steel can be forged into a hammer without falling apart or cracking everywhere its great. It just needs to drive a nail in. This hammer doesn't need to be hardened. Its just a claw hammer. As long as the claw is bigger than the nail it won't bend.
@@honkie247 the rebar was most like reclaimed from train rail or ship breaking. That is very suitable steel for reclaiming much better than most mild steel or a36 structural steel available at a typical steelyard.
This hammers cost a fraction of other more " perfect" hammers. This is an undevelopped country.... people cant afford expensives long duration hammers Workers are smart and efforced... my respects❤😊
@@davidhamm5626 well yeah cast iron is brittle but why not just melt some meteorite iron with a little 24k gold for added toughness and luster. That would work good. Just melt it in a cast-iron stew pot over a camp fire then pour it out in a open mold like on... game of throns it must be how you make metal things. I saw it on the tv
Somewhere else in pakistan someone is making rebar out of knackered hammers.
Brilliant!
That’s how my great great grandfather made stuff in the late 1800s
Calm down. This is how they are still made it china.
@Dr.Kraig_Ren made in India
Hammers made from scrap metal are always scrap
Class B or C .Class A if it came directly from mining company

Worked for Iowa steel and wire. Rebar is bottom of the barrel shit steel with a specification.

Rebar can be heat treated if dunked in brine when yellow hot, but yes it's not the proper steel for a hammer head.

Ha ha those are the hammers you see at dollar tree for 99 cents and fall apart the first time you use them junk
The 99 cent ones are cast metal....

Depends on what you want out of it I suppose. Some of my hammers cost me around 4 to $500.

Half the comments on these videos are westerners talking shit on the manufacturing - they get the job done!
Cripes. Nine cycles of removing the flashing and punching the center hole.
Very good information
Thanks
I don’t think that these people care about optimizing production processes. The product needs to be as cheap as possible.
They are should focus worker safty.

the claw on a hammer is almost obsolete in the US
You’d think they’d toss the finished forgings in brine?

I am thinking why not melt the iron bars in a foundary and pour the molten iron into an hammer head mold and finish it from there on, less process 😊
Cast iron is too brittle for this use.If you hit an engine block or cylinder head , with a hammer, you will see what i mean.

Cast steel
Its a lot less process to reforge a piece of rail steel or chain steel or any steel than to cast a steel hammerhead.
