Abstract

A method by which a steel component can be produced, which is provided with a metallic coating which adheres well and which provides protection against corrosion, from a flat steel product produced from a steel material containing 0.3-3 wt.-% manganese and having a yield point of 150-1100 MPa and a tensile strength of 300-1200 MPa coated with an anti-corrosion coating which comprises a coating of ZnNi alloy which is electrolytically deposited on the flat steel product, which coating is composed in a single phase of γ-ZnNi phase and which contains, as well as zinc and unavoidable impurities, 7-15 wt.-% nickel.
