Patent ID: 10081857

Abstract:
A metallic flat product is disclosed which is subjected to surface finishing by hot-dip coating and which is preferably composed of steel. The metallic flat product includes a metallic alloy layer (11) and a metallic surface layer (12′), which metallic alloy layer and metallic surface layer differ from one another in terms of their chemical composition. The two layers (11, 12′) are produced in a one process step and define a continuous transition region (13) in which a mixture of the two different chemical compositions is present. The metallic alloy layer (11) has a thickness of less than 8 μm, preferably less than 6 μm, and the surface layer (12′) is formed from aluminum or zinc. The flat product has an improved coating, by means of which the flat product more effectively satisfies the requirements with regard to good deformability and has good anti-corrosion protection.
