Abstract:
A non-oriented electrical steel sheet contains Cr: 0.3 mass % to 5.3 mass %, Si: 1.5 mass % to 4 mass %, Al: 0.4 mass % to 3 mass %, and W: 0.0003 mass % to 0.01 mass %. A C content is 0.006 mass % or less, a Mn content is 1.5 mass % or less, a S content is 0.003 mass % or less, and a N content is 0.003 mass % or less, and the balance is composed of Fe and inevitable impurities.
Abstract:
A non-oriented electrical steel sheet includes: C: 0.005 mass % or less; S: 0.003 mass % or less; N: 0.003 mass % or less; Si: 2.0 mass % or more and less than 4.5 mass %; Al: 0.15 mass % or more and less than 2.5 mass %; and Cr: 0.3 mass % or more and less than 5.0 mass %; and a balance being composed of Fe and inevitable impurities; and a Cr-oxide-containing layer having a thickness of not less than 0.01 μm nor more than 0.5 μm on a surface side, in which when [Si], [Al], and [Cr] are set to the Si content, the Al content, and the Cr content (mass %) of the non-oriented electrical steel sheet respectively, and t is set to a sheet thickness (mm) of the non-oriented electrical steel sheet, 10 mass %≦2[Si]+2[Al]+[Cr]
Abstract:
