Hot stamping of boron alloyed steels has achieved high significance for the production of high strength automotive body parts. The number of production facilities is increasing where the conventional process with the baron alloyed steel 22MnB5 in its coated or uncoated variant is used. With hot stamping it was the first time that a heat treatment process entered the press shop and thus an adjustment of the part properties got feasible. As the equipment now is available, there are still many possibilities to improve the process efficiency or to reach an improved part performance. This paper will give an overview on the latest developments in the field of hot stamping beginning from heating to tool technologies. Special attention will be paid to alternative sheet materials which lead to special part properties, giving hot stamping new fields of application in the car body.
