ABSTRACT:
A cold-rolled steel strip having a combined silicon and aluminum content no greater than about 1.5 wt. % is subjected to processing including a continuous decarburization anneal after temper rolling. The strip is stamped into motor core laminations and stress relief annealed. The resulting lamination has magnetic properties comparable to a lamination having a much higher silicon and silicon plus aluminum content.
