Abstract

The steel may be hot rolled directly from ingot to hot band at lower than conventional temperatures without adversely affecting the magnetic properties thereof, when it has a manganese to sulfur ratio of not more than 2.5 and preferably about 1 to less than 2.5. Hot rolling is conducted at a temperature of not more than 1260 DEG C (2300 DEG F) and preferably 1204 DEG C (2200 DEG F) to less than 1269 DEG C (2300 DEG 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. The composition and processing are otherwise conventional.
