Electrical steel, usually referring to cold rolled electrical steel, can be divided into two major categories including grain oriented electrical steel and non-oriented electrical steel. Grain oriented electrical steel, with its easy magnetization direction parallel to the rolling direction, has excellent magnetic properties in this direction including low core loss, high permeability and low magnetostriction and is widely used in the transformer industry. Further it can obtain lower core loss by domain renement treatment. Meanwhile non-oriented electrical steel, featured by random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry.
Magnetic Properties The magnetic properties of the product is featured by its low core loss, high permeability and excellent application performance.
The good thickness tolerance is characterized by small difference in thickness in a direction parallel to the direction of rolling, small difference in thickness in a direction perpendicular to the direction of rolling, and high lamination factor.
The product is suitable for punching and cutting with excellent dimensional tolerance.
The insulation coating has small color deviation, good adhesiveness and excellent resistance to heating and corrosion with high insulation coating resistance. There are several types of insulation coating available for production. According to the test results performed by the professional inspection organizations, the contents of hazardous substances comply with all the prevailing international and domestic environment protection laws and regulations including EU RoHS and REACH regulations.
Surface Coating Designation
The surface coating is usually T4, and the grade with sufx such as "H4", "K", "L", "V" and "Z" refers to special coating designation.
H4: chromium free semi organic coating
K: chromium free and water soluble thick coating, equivalent to C5 according to IEC 60404-1-1
L: chromium free and water soluble extreme thick coating, equivalent to C6 according to IEC 60404-1-1
V: chromium free and water soluble thin coating, equivalent to C4 according to IEC 60404-1-1
Z: chromium free, water soluble and self-bonding coating, equivalent to C3 according to IEC 60404-1-1
