ABSTRACT OF THE DISCLOSURE A method for producing grain oriented silicon steel wherein the steel may be hot rolled directly from ingot to hot band at lower than conventional temperatures without adversely affecting the magnetic properties thereof. In addition, the steel is characterized by a manganese to sulfur ratio less than about 2.5 and preferably about 1 to less than about 2.5. Hot rolling is conducted at a temperature of less than 2300°F and preferably 2200 to less than 2300°F. Preferably the steel contains copper in an effective amount up to 0.4% by weight and preferably about 0.2 to less than 0.58% by weight.
