Abstract

A non-oriented electromagnetic steel sheet contains 0.005 wt.% or less C, 0.2 wt.% or less P, 0.005 wt.% or less N, 4.5 wt.% or less Si, 0.05 to 1.5 wt.% Mn, 1.5 wt.% or less Al and 0 . 001 wt.% or less S, at least one element selected from the group of 0.001 to 0.05 wt.% Sb, 0.002 to 0.1 wt.% Sn, 0.0005 to 0.01 wt.% Se and 0.0005 to 0.01 wt. % Te; and the balance being Fe and inevitable impurities. The non-oriented electromagnetic steel sheet is produced by the steps of: hot-rolling a slab to form a hot-rolled steel sheet, cold-rolling the hot-rolled steel sheet to form a cold-rolled steel sheet; and finish annealing the cold-rolled steel sheet.
