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.
