Abstract (en)

[origin: WO2019037838A1] The invention relates to a use of a Q&P steel for producing a shaped component (2) for high-wear applications, wherein the Q&P steel has a hardness of at least 230 HB, in particular at least 300 HB, preferably at least 370 HB, and a bending angle α of at least 60°, in particular at least 75°, preferably at least 85°, determined according to VDA238-100, and/or a bending ratio of r/t<2.5, in particular r/t<2.0, preferably r/t<1.5, wherein t corresponds to the material thickness of the steel and r corresponds to the (inner) bending radius of the steel.
