发明名称 PROCESS FOR PRODUCING COMPONENTS HAVING REGIONS OF DIFFERING DUCTILITY
摘要 The invention relates to a process for producing sheet steel components having regions of differing ductility, in which either a sheet metal plate composed of a hardenable steel alloy is used to produce a component by deep-drawing and the deep-drawn component is then at least partially austenitized by a heat treatment and subsequently quench hardened in a die or the plate is at least partially austenitized by a heat treatment and shaped in the hot state, and is quench hardened during or after this, with the sheet metal plate having a zinc-based cathodic corrosion protection coating, characterized in that in regions of a desired higher ductility of the component, at least one additional sheet is attached to the plate, situated so that during the heat treatment, the plate is heated to a lesser degree there than in the remaining region.
