Buy a chunk of O-1 tool steel, mild carbon steel will not harden correctly due to not enough carbon in the material. [Reply]  [No Email]

You can heat and quench mild steel to make it hard (brittle), but you have use better steel if you want to increase tensile strength. [Reply]  [No Email]

This would not be your torch. [Reply]  [No Email]

You can heat it, quench it, heat it again, quench it again until you're tired of it and you won't change the hardness or strength of it. Not even one little bit. [Reply]  [No Email]

It's usually made from low carbon steel, and you would need to carborize it to harden it. I keep a can of kasenit around the shop for this purpose. Not practical for big stuff, but does a good job with just a torch and a bucket of water. [Reply]  [No Email]
