Soft magnetic steel sheet and soft magnetic steel sheet, and those production mannered null masses for low temperature oxide skin formation

摘要

PROBLEM TO BE SOLVED: To provide a method for imparting an inexpensive rust preventive function substituted for plating to a soft magnetic steel sheet, and to improve the blanking properties of a soft magnetic steel sheet.;SOLUTION: The soft magnetic steel sheet for forming a low temperature oxide film has a composition comprising, by mass, ≤0.01% C, 0.05 to 3.0% Si, ≤0.5% Mn, ≤0.01% S, 0.0005 to 2.0% acid soluble Al, ≤0.1% P and ≤0.005% N, and the balance substantially Fe with impurities.;COPYRIGHT: (C)2006,JPO&NCIPI
