Abstract

1382395 Silicon steel ALLEGHENY LUDLUM INDUSTRIES Inc 9 Feb 1973 [11 Feb 1972] 6441/73 Heading C7A Grain oriented silicon steel contains 0.24- 0À75% Cu, 2À2-4% Si, carbon in an amount usual in silicon steels and unavoidable impurities, the balance being Fe. Silicon steels containing 0À24-0À75% Cu are amenable to cold rolling in a single pass.
