Abstract

La présente invention porte sur une tôle d'acier électromagnétique non orienté ayant des propriétés magnétiques supérieures et des propriétés mécaniques supérieures et également une qualité de tôle d'acier supérieure pouvant être obtenue à un faible coût par la formation d'une composition de composants qui contient, en pourcentage en masse, 5,0 % ou moins de Si, 2,0 % ou moins de Mn, 2,0 % ou moins d'Al et 0,05 % ou moins de P dans une plage qui satisfait à la formule (1) et qui contient en outre 0,008-0,040 % de C, 0,003 % ou moins de N et 0,04 % ou moins de Ti dans une plage qui satisfait à la formule (2), le reste étant constitué de Fe et d'impuretés inévitables. 300 = 85[Si %] + 16[Mn %] + 40[Al %] + 490[P %] = 430 (1) 0,008 = Ti* < 1,2[C %] (2) Ici, Ti* = Ti - 3,4[N %]
