<P>PROBLEM TO BE SOLVED: To provide a nonoriented silicon steel sheet in which the problem that high electric resistance obtainable by high Si-high Cr incorporation is not sufficiently made the most of is advantageously solved, and which has excellent high frequency magnetic properties in the region of several hundreds to 10 kHz. <P>SOLUTION: The steel sheet has a composition comprising, by mass, 2.5 to 10.0% Si, 1.5 to 20.0% Cr, ≤0.0060% C, ≤0.0020% N, ≤0.0050% S, ≤0.0050% Ti and ≤0.0050% Nb, and comprising one or two kinds selected from Sb and Sn in the ranges of >0.04 to 1.0% and >0.06 to 1.0%, respectively, and the balance Fe with inevitable impurities. <P>COPYRIGHT: (C)2004,JPO |
