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 a 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.
摘要:
A flat steel product, intended to be formed into a component by hot press forming and having a base made of steel, onto which a metal anti-corrosion coating of a Zn or a Zn alloy is applied. A separate finishing coat is applied to at least one of the free surfaces of the flat steel product. The finishing coat includes at least one base metal compound (oxide, nitride, sulphide, sulphate, carbide, carbonate, fluoride, hydrate, hydroxide, or phosphate). Also, a method enabling the production of a flat steel product of this kind.
