摘要：
The invention relates to a flat steel product, which is intended to be shaped into a component by hot-press forming and which has a base layer made of steel, onto which a metal protective layer that protects against corrosion is applied, said protective layer being made of Zn or a Zn alloy. This is achieved according to the invention in that a separate cover layer containing an oxide, nitride, sulfide, carbide, hydrate, or phosphate compound of a base metal is applied to at least one of the free surfaces of the flat steel product. The invention further relates to a method that allows such a flat steel product to be produced and to a method that makes it possible to produce a component from such a flat steel product.
