The invention relates to the use of a Q&P steel for production of a formed component (2) for high-wear applications, wherein the Q&P steel has a hardness of at least 230 HB, especially at least 300 HB, preferably at least 370 HB, and a bending angle &#x3b1; of at least 60&#xb0;, especially at least 75&#xb0;, preferably at least 85&#xb0;, determined to VDA238-100, and/or a bending ratio of r/t&#x3c;2.5, especially r/t&#x3c;2.0, preferably r/t&#x3c;1.5, where t corresponds to the material thickness of the steel and r to the (inner) bending radius of the steel.

Use of a Q and P steel for producing a shaped component for high-wear applications

A method for producing a component made of a steel product coated with an Al&#x2014;Si protective coating, includes:

Temporary corrosion protection layer

A steel component having a steel substrate containing 0.3-3 wt.-% manganese, and an anti-corrosion coating applied to the steel substrate including a coating layer having at least 70 mass-% &#x3b1;-Fe(Zn,Ni) mixed crystal, the remainder being intermetallic compounds of Zn, Ni and Fe, and which has at its free surface a Mn-containing layer in which the Mn is present in metallic or oxidic form.

Steel component provided with a metallic coating giving protection against corrosion

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 &#x3b3;-ZnNi phase and which contains, as well as zinc and unavoidable impurities, 7-15 wt.-% nickel.
