What is Electrical steel?

Electrical steel, usually referring to cold rolled electrical steel. It can be divided into two major categories, including grain oriented electrical steel and non-oriented electrical steel.

Grain oriented electrical steel(GO), with its easy magnetization direction parallel to the rolling direction, has excellent magnetic properties in the rolling direction, including low core loss, high permeability and low magnetostriction. Then it is widely used in the transformer industry. Further it can obtain lower core loss by domain refinement treatment.

Meanwhile non-oriented electrical steel, featured by random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry.
