Hot stamping, also called hot forming or press hardening, is the process of forming metal while it is very hot (in excess of 900 C degrees) and then quenching it (cooling it quickly) in the die. The process converts low-tensile strength metal to a very high-strength steel (150 to 200 kilopounds per ...
