Abstract: The invention relates to a steel component comprising a steel substrate having an anticorrosion coating present at least on one side of the steel substrate. This anticorrosion coating comprises a manganese-containing alloy layer. The manganese-containing alloy layer here forms the closest alloy layer of the anticorrosion coating to the surface. Moreover the manganese-containing alloy layer comprises iron and a further metal.

Abstract: A component including a steel substrate having a structure that can be transformed into a martensitic structure, a metallic intermediate layer which covers the steel substrate and has a main constituent of titanium and an anticorrosion coating covering the intermediate layer, wherein the anticorrosion coating includes one or more layers and at least the layer of the anticorrosion coating adjoining the metallic intermediate layer is metallic and differs in terms of material from the intermediate layer.

Abstract: A metal sheet component including (in % by weight) C: up to 0.5%, Si: 0.05-1%, Mn: 4-12%, Cr: 0.1-4%, Al: up to 3.5%, N: up to 0.05%, P: up to 0.5%, S: up to 0.01%, Cu, Ni: in total up to 2%, Ti, Nb, V: in total up to 0.5%, rare earth metals: up to 0.1%, and as a remainder, Fe and unavoidable impurities, wherein the content % C of C and the content % Cr of Cr meet the following condition: (10×% C)+% Cr<5.5%. In order to manufacture a metal sheet component, a flat steel product is heated to a heating temperature, which is at least 200° C. and at most 800° C., and then formed into the component by hot forming the flat steel product heated to the heating temperature, with the structure of the hot-formed metal sheet component having 5-50% by volume austenite and, as the remainder, martensite, tempered martensite and/or ferrite, wherein the ferrite proportion can also be 0, and the average grain diameter of the structure is less than 5 ?m.
