摘要: A flat steel product which is provided for forming into a component by hot pressing and which has a base layer of steel on which is applied a Zn or Zn alloy metallic protective coating for protecting against corrosion. On at least one of the free surfaces of the flat steel product, a separate cover layer is applied which contains an oxide, nitride, sulphide, carbide, hydrate or phosphate compound of a base metal. In addition, a method which allows the production of such a flat steel product, and a method which allows the production of a component from such a flat steel product.
