Abstract: A method of production non grain-oriented Fe—Si steel sheet is provided. The method includes the steps of melting a steel composition that contains in weight percentage: C≦0.006, 2.0≦Si≦5.0, 0.1≦Al≦3.0, 0.1≦Mn≦3.0, N≦0.006, 0.04≦Sn≦0.2, S≦0.005, P≦0.2, Ti≦0.01, the balance being Fe and other inevitable impurities, casting said melt into a slab, reheating said slab, hot rolling said slab, coiling said hot rolled steel, optionally annealing the hot rolled steel, cold rolling, annealing and cooling the cold rolled steel down to room temperature.
