  • Patent number: 5258080
    Abstract: The invention relates to a non-oriented electrical strip having high proportions of cube or cube on face texture, a polarization of J 2500>1.7 T and a low core loss, and also to a process for its production. A steel slab, containing max. 0.025% C, less than 0.1% Mn, 0 to 0.15% boundary-surface-active elements and Si and Al in such a way that the relations (% Si)+2(% Al)>1.6% and (% Si)+(% Al)<4.5% are met, balance iron, is hot rolled to a thickness not lower than 3.5 mm. The resulting hot rolled strip is then cold rolled with a degree of reduction of at least 86% without intermediate recrystallization annealing and, if necessary, final annealed.
