Abstract
A sheet metal component made of a hot-formed flat steel product including a steel substrate consisting of, in mass. %, C: 0.1-0.4%, Mn: 0.5-3.0%, Si: 0.05-0.5%, Cr: 0.005-1.0%, B: 0.00050.01% and optionally one or more of V, Ti, Nb, Al, Ni, Cu, Mo, and W, where the contents of the respective optionally present alloy element are V: 0.001-0.2%, Ti: 0.01-0.1%, Nb: 0.001-0.1%, Al: 0.01-0.2%, Ni: 0.01-0.4%, Cu: 0.01-0.8%, Mn: 0.002-1.0%, W: 0.001-1.0%, and the remainder iron and unavoidable impurities, wherein the unavoidable impurities include contents of less than 0.1% P, less than 0.05% S, and less than 0.01% N, and an Al corrosion protection layer applied to the steel substrate, wherein the component is optionally hardened. An adhesive section having an SDR value of 3-30%, determined according to ISO 25178, is provided on the free outer face of the corrosion protection coating for adhering the sheet metal component to another component.
