ABSTRACT OF THE DISCLOSURE A method is provided for producing thin gauge cube-on-edge grain-oriented silicon steel from hot-rolled band to final gauge in two cold reduction steps. The two-stage cold reduction process requires an intermediate anneal between the two stages of cold reduction and requires that the cold working of the desired intermediate gauge to final gauge include a cold reduction of at least 55% to provide a final gauge product of nominally 0.007 inch. A cube-on-edge grain-oriented silicon steel product is also provided.
