NON-ORIENTED ELECTRICAL STEEL SHEET AND MANUFACTURING METHOD THEREOF |
| 摘要 |
A non-oriented electrical steel sheet comprising, Si: not less than 1.0 mass % nor more than 3.5 mass %, Al: not less than 0.1 mass % nor more than 3.0 mass %, Ti: not less than 0.001 mass % nor more than 0.01 mass %, Bi: not less than 0.001 mass % nor more than 0.01 mass %, wherein Expression (1) is satisfied when a Ti content (mass %) is represented as [Ti] and a Bi content (mass %) is represented as [Bi]: [Ti]≦0.8×[Bi]+0.002 . . . (1). |

1. A non-oriented electrical steel sheet, containing:
Si: not less than 1.0 mass % nor more than 3.5 mass %; Al: not less than 0.1 mass % nor more than 3.0 mass %; Mn: not less than 0.1 mass % nor more than 2.0 mass %; Ti: not less than 0.001 mass % nor more than 0.01 mass %; and Bi: not less than 0.001 mass % nor more than 0.01 mass %, a C content being 0.01 mass % or less, a P content being 0.1 mass % or less, a S content being 0.005 mass % or less, a N content being 0.005 mass % or less, and a balance being composed of Fe and inevitable impurities, wherein when a Ti content (mass %) is represented as [Ti] and a Bi content (mass %) is represented as [Bi], Expression (1) below is satisfied:
[Ti]≦0.8×[Bi]+0.002 Expression(1). |
