AHSS

Advanced high strength steels (AHSS) are work materials with tensile strengths ranging from ~780 MPa and higher. The demands on tooling for AHSS are the highest of any blanking and forming application. Due to the high strength causing higher cutting force, contact pressure and cyclic load, traditional wear mechanism as abrasive wear are moving towards more chipping, galling and plastic deformation. In order to prolong tool life it is essential to use tooling material with sufficient resistance against these failures.

From an environmental standpoint, advanced high strength steels can significantly reduce weight in producing a detail, allow for smaller amounts of raw material to be used and consume less energy. At the same time, less energy is needed to transport the steel and the steel itself is also totally renewable. There are also applications where advanced high strength steel makes it possible to exclude tempering furnaces from the manufacturing process, and consequently the environmental hazards involved.
