Non-oriented electrical steel sheet and method of manufacturing non-oriented electrical steel sheet

Abstract

This oriented electrical steel sheet is a non-oriented electrical steel sheet consisting of, in mass %: C: not less than 0.0001% and not more than 0.0040%, Si: more than 3.0% and not more than 3.7%, sol.Al: not less than 0.3% and not more than 1.0%, Mn: not less than 0.5% and not more than 1.5%, Sn: not less than 0.005% and not more than 0.1%, Ti: not less than 0.0001% and not more than 0.0030%, S: not less than 0.0001% and not more than 0.0020%, N: not less than 0.0001% and not more than 0.003%, Ni: not less than 0.001% and not more than 0.2%, P: not less than 0.005% and not more than 0.05%, with a balance consisting of Fe and impurities, in which a resistivity ρ at room temperature ≧60 μΩcm, and saturation magnetic flux density Bs at room temperature ≧1.945 T are established, and the components contained satisfy 3.5≦Si+(⅔)×sol.Al+(⅕)×Mn≦4.25.
