Batch annealed, semi-processed and fully processed motor lamination steels are made by processes which subject a slab having an ultra low carbon composition (less than 0.01%) to at least the following steps: hot rolling with an austenite finishing temperature, coiling at a temperature ranging from 1300 DEG -1450 DEG F., and light temper rolling (less than 1.0% reduction) or leveling; reheating at a temperature less than 2300 DEG F., hot rolling with a ferrite finishing temperature, coiling at a temperature less than 1200 DEG F., and light temper rolling or leveling; or hot rolling with a ferrite finishing temperature, coiling at a temperature ranging from 1100 DEG -1350 DEG F. without a subsequent hot band anneal, and light temper rolling or leveling.
