FORMED SHEET-METAL COMPONENT AND METHOD FOR PRODUCING THE FORMED SHEET-METAL COMPONENT

摘要

The invention relates to a formed sheet-metal component, produced by hot forming and press hardening from a hardenable one-piece, single-material steel alloy, wherein the formed sheet-metal component (1) has a tensile strength greater than 1200 MPa, in particular greater than 1350 MPa, and has a bending angle greater than 60° in the case of a wall thickness of 0.5 to 1.5 mm or a bending angle greater than 45° in the case of a wall thickness of 1.5 to 2.5 mm, characterized in that a number of martensite layers lying one on top of the other are formed in the formed sheet-metal component, wherein a martensite layer lying on the outside of the formed sheet-metal component has a greater ductility than a martensite layer lying thereunder.
