This facilitates shaping, stamping or forming processes, and allows the metal to be cut more … WebThrough hardening occurs via heat treatment of medium and high carbon steels (>0.25% carbon). First, ovens heat the steel above its critical temperature, which lies between 1500°F-1900°F depending on alloy. Second, the material is cooled rapidly by dunking the material in water or oil in a process known as quenching.

WebInduction hardening. Induction hardening is a surface hardening technique which uses induction coils to provide a very rapid means of heating the metal, which is then cooled rapidly, generally using water. This creates a “case” of martensite on the surface. A carbon content of 0.3–0.6 wt% C is needed for this type of hardening. Laser ...
