Saturation magnetization to be high the non directivity electromagnetic steel sheet null whose iron loss

摘要

PROBLEM TO BE SOLVED: To provide a non-oriented magnetic steel sheet having high saturation magnetization and a low core loss. ;SOLUTION: A non-oriented magnetic steel sheet having high saturation magnetization and a low core loss contains 0.005 wt.% C or lower, 1.0-3.0 wt.% Si, 0.05-1.0 wt.% Mn, ≤0.2 wt.% P, ≤0.005 wt.% N (including 0 wt.% or lower), 0.1-1.0 wt.% Al, ≤3.5 wt.% Si or Al (Si+Al), ≤0.0009 wt.% S (including 0 wt.%), 0.001-0.05 wt.% Sb or Sn (Sb+Sn/2), and the remaining substantially Fe.;COPYRIGHT: (C)1999,JPO
