PROBLEM TO BE SOLVED: To produce a nonoriented silicon steel sheet reduced in fine nitrides checking the growth of grains and excellent in magnetic properties. SOLUTION: This nonoriented silicon steel sheet is composed of, by weight, <=0.005% C, 0.05 to 1.0% Si, 0.1 to 1.0% Mn, <=0.2% P, <=0.001% N, <=0.02% S, 0.05 to 1.0% sol.Al and <=0.0015% Ti, and the balance substantial Fe. |
