<p>PROBLEM TO BE SOLVED: To provide a means for producing a nonoriented silicon steel sheet good in magnetism. SOLUTION: As to this nonoriented silicon steel sheet excellent in magnetism, in a nonoriented silicon steel sheet containing components of, by weight, <=0.005% C, 0.1 to 0.5% Mn, 0.7 to 1.7% Si and >1.6 to 2.5% Al so that 2.5%<=Si+Al<=3.7 is satisfied and the balance Fe with inevitable impurity elements, the value of B50/Bs obtained by dividing the magnetic flux density B50 in the product sheet by the saturation magnetic flux density Bs satisfies B50/Bs>=0.83.</p> |
