PROBLEM TO BE SOLVED: To provide a nonriented silicon steel sheet high in magnetic permeability and to provided a method for producing the same. SOLUTION: This nonoriented silicon steel sheet excellent in magnetic permeability contains, in steel, by weight, 0.1 to 1.0% Si, 0.1 to 0.8% Mn and 0.1 to 1.0% Al, and the balance Fe with inevitable impurities, has αγ transformation and has electrical resistivity of 10×10-8 Ωm to 32×10-8 Ωm and magnetic permeability μ 15/60 of 1,500 (Gauss/Oe) or more. |
