Abstract (en)
[origin: WO2018019602A1] The invention relates to a steel strip for producing a non-oriented electrical steel. To achieve greatly improved frequency-independent magnetic properties, in particular greatly reduced hysteresis losses, in comparison with known electrical steels, the following alloy composition in wt% is proposed: C: ≤0.03, Al: 1 to 12, Si: 0.3 to 3.5, Mn: >0.25 to 10, Cu: >0.05 to 3.0, Ni: >0.01 to 5.0, total of N, S and P: at most 0.07, remainder iron and smelting-related impurities, with the optional addition of one or more elements from the group Cr, Mo, Zn and Sn, wherein the steel strip has an insulation layer substantially consisting of Al2O3 and/or SiO2 with a thickness in the range from 10 µm to 100 µm. The invention also relates to a method for producing such a steel strip.
