Abstract: A method for producing a steel component provided with a metallic coating which protects against corrosion, in which a steel flat product, produced from an alloyed heat-treated steel, is coated with an Al coating which contains ?85% wt. Al and optionally ?15% wt. Si, a Zn coating with ?90% wt. Zn, and a top layer, the main constituent of which is at least one metal salt of phosphoric acid or diphosphoric acid and which additionally can contain contents of up to 45% of an Al:Zn ratio as well as optionally metal oxides, metal hydroxides and/or sulphur compounds, the steel flat product is heat treated at ?750° C., and the steel component is hot-formed from the heated steel flat product. The hot-formed steel component is cooled at a cooling rate sufficient to form a tempered or martensitic structure.

Abstract: A method for producing a steel component provided with a metallic coating which protects against corrosion, comprising the following steps: coating a steel flat product, produced from a low-alloy heat-treated steel, with an Al coating which contains at least 85% wt. Al and optionally up to 15% wt. Si; coating the steel flat product provided with the Al coating with a Zn coating which contains at least 90% wt. Zn; heating the steel flat product to a hot-forming temperature which is at least 750° C.; hot forming the heated steel component made from the steel flat product; and cooling the hot-formed steel component sufficiently quickly to form a tempered or martensitic structure.
