ORIENTED ELECTROMAGNETIC STEEL SHEET AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an oriented electromagnetic steel sheet responding to requests of further low iron loss while preventing coating damage during electron beam irradiation.SOLUTION: An oriented electromagnetic steel sheet contains, by mass%, Si:2.0 to 8.0% and Mn:0.005 to 1.0%, has the Al content in forsterite coating-containing steel sheet of less than 100 mass ppm and the S content of 40 mass ppm or more and the balance Fe with inevitable impurities.
