Abstract (en)

[origin: EP2612942A1] The non grain-oriented electrical steel strip or sheet comprises a steel in addition to iron and unavoidable impurities, silicon (2.4-3.4 wt.%), aluminum (2 wt.%), manganese (1 wt.%), carbon (0.006 wt.%), nitrogen (0.006 wt.%), sulfur (0.006 wt.%), titanium (0.1-0.5 wt.%), and phosphorus (0.1-0.3 wt.%), where a ratio of titanium to phosphorus is 1.43:1.67. The electrical steel strip or sheet has a hysteresis loss P(1/400) at a polarization of 1 tesla and a frequency of 400 Hz at a thickness of the electrical steel strip or sheet of 0.5 mm of 65 W/kg and at a thickness of 0.35 mm of 45 W/kg. Independent claims are included for: (1) a component for electrotechnical applications; and (2) a method for producing a non grain-oriented electrical steel strip or sheet.
