Sheet Metal Component and Method for Producing Same

A method for producing a sheet metal component, comprising the following work steps:

• a) providing a hot-rolled flat steel product comprising a steel substrate, which, in mass. %, consists of:
• C:
• 0.1-0.4%, Mn:
• 0.5-3.0%, Si:
• 0.05-0.5% Cr:
• 0.005-1.0%, B:
• 0.0005-0.01%, optionally one or more of alloy elements selected from the group consisting of V, Ti, Nb, Al, Ni, Cu, Mo, and W, wherein V:
• 0.001-0.2%, Ti:
• 0.001-0.1%, Nb:
• 0.001-0.1%, Al:

01-0.2%, Ni:

• 0.01-0.4%, Cu:
• 0.01-0.8% Mo:
• 0.002-1.0%, W:
• 0.001-1.0%, and a remainder of iron and unavoidable impurities;
• b) optional pickling of the hot rolled flat steel product;
• c) cold rolling the hot rolled flat steel product to form a cold strip, wherein the cold rolling is optionally performed in more than one rolling step, and wherein, optionally, the respective cold-rolled strip obtained after the previous cold rolling step is optionally annealed between the cold rolling steps;
• d) coating the cold strip with a corrosion protection coating based on aluminum;
• e) skin-pass rolling the cold strip provided with the corrosion protection layer,
• f) sectioning off a blank from the skin-pass rolled cold strip;
• g) heating the blank to a hot forming temperature of 850-950° C.;
• and
• h) hot forming the heated blank to form the sheet metal component,
• wherein, by means of the cold rolling (work step c)) and/or the skin-pass rolling (work step e)), at least a portion of an outer surface of the corrosion protection layer has a surface texture having a maximum wavelength of 0.1-1.0 mm.
