Abstract

The increasing demand for high strength steels regarding light weight construction design for the body in white is enforcing the automotive industry to onset more and more innovative forming technologies due to the reduced formability of such high strength steel grades. The hot stamping of boron manganese steels is hereby one of the main forming processes to be named. Besides the commonly used forming strategy where a homogeneous distribution of the material parameters is achieved, the partial press hardening is an innovative technology to be able to manufacture parts with a locally different strength and ductility profile. The thermal properties needed for this kind of process strategy had been determined using a heatable quenching tool developed at the Chair of Manufacturing Technology and are further discussed in this paper.
