ABSTRACT:
A method for improving the magnetic permeability and core loss of grain oriented silicon steel; the improvement in these magnetic properties is achieved by conducting annealing prior to cold rolling at a temperature above the temperature at which transformation to austenite occurs and thereafter quenching said steel.
