    摘要: 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.
