METHOD FOR PRODUCING A STEEL COMPONENT FOR A VEHICLE

A method of producing a component for a vehicle may involve providing a workpiece comprised of a heat-treatable steel material with a zinc-containing coating on both sides, at least partly heating the workpiece to a temperature above Ac1, inserting the at least partly heated workpiece into a hot-for...

Beschreibung
Zusammenfassung:	A method of producing a component for a vehicle may involve providing a workpiece comprised of a heat-treatable steel material with a zinc-containing coating on both sides, at least partly heating the workpiece to a temperature above Ac1, inserting the at least partly heated workpiece into a hot-forming and/or press-hardening mold comprising at least one punch and at least one die, and closing the mold by relative movement of the punch and/or the die and hot-forming and/or press-hardening the workpiece. At least a region of the heated workpiece may be cooled in the closed mold such that there is at least partial formation of a hardened microstructure. The workpiece may have a first side with a smaller coating thickness of the zinc-containing coating compared to the second side of the workpiece."
