18RK085/23RK075/27RK090/30RK105 CRGO Domamin Refined High Induction Description

Electrical steel, usually referring to cold rolled electrical steel, can be divided intotwo major categories including grain oriented electrical steel and non-orientedelectrical steel. Grain oriented electrical steel, with its easy magnetizationdirection parallel to the rolling direction, has excellent magnetic properties in thisdirection including low core loss, high permeability and low magnetostriction andis widely used in the transformer industry. Further it can obtain lower core lossby domain refinement treatment. Meanwhile non-oriented electrical steel.featured by random distribution of grain orientation and magnetic isotropy, iswidely applicable to the motor industry.
