Tempering metal ?
A question of those that know. I plan to twist a piece of 1/2" X 2" flat strap stock 90 degrees only, by heating it with a torch and twisting. I want it to retain its strength, yet be able to drill a hole or two in it if need be.
To retain the strength of the metal, should I let it cool naturally, plunge it into water ? oil ? .
How does all that work ?
Thanks in advance.
