Hot stamping (also known as press hardening, hot press forming, or hot forming die quenching) is a relatively new technology which allows ultra-high strength steels (typically 22MnB5 boron steel[1]) to be formed into complex shapes, which is not possible with regular cold stamping operations.[2] This process is commonly used for the production of automotive body in white components because its advantages align with the design criteria of modern passenger vehicles. For high strength aluminium alloys, there is a similar hot forming process, which has different metallurgical transformations - Hot Form Quench.[3]
