摘要 |
A high-strength non-oriented electrical steel sheet contains: in mass%, C: 0.010% or less; Si: not less than 2.0% nor more than 4.0%; Mn: not less than 0.05% nor more than 0.50%; Al: not less than 0.2% nor more than 3.0%; N: 0.005% or less; S: not less than 0.005% nor more than 0.030%; and Cu: not less than 0.5% nor more than 3.0%, a balance being composed of Fe and inevitable impurities. An expression (1) is established where a Mn content is represented as [Mn] and a S content is represented as [S], and not less than 1.0×10 4 pieces nor more than 1.0×10 6 pieces of sulfide having a circle-equivalent diameter of not less than 0.1 µm nor more than 1.0 µm are contained per 1 mm 2 . |
