New case hardening/tempering techniques
I'm trying to research different techniques of hardening steel as I am interested in how to best temper steel. Or, as I believe, there is no "best" way to do it because different purposes call for different techniques! I have found boronizing with borocoat today, so I got curious.
Please share any case hardening techniques you know. Even if I have already heard of them, I would like to learn more!
