摘要： The present invention relates to a semiprocessed nonoriented magnetic steel sheet which is used in iron cores of motors and transformers, finished to a final product by rolling having a reduction rate of 2 to 18% after final annealing by a manufacturer, and assures desired magnetic characteristics due to coarsening of crystal grains during strain-relief annealing after processing by a user. The excellent magnetic characteristics can be achieved by increasing lubrication during second cold rolling so as to satisfy the equation: e.sub.c .ltoreq.e.sub.s .ltoreq.1.18e.sub.c wherein e.sub.s represents a strain value at the surface layer of the steel sheet and e.sub.c represents a strain value at the central layer.
