Product introduction
Electrical steel,usually referring to cold rolled electrical steel, can be divided into two major categories including qrain 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 refinement treatment. Meanwhile non-oriented electrical steel featured by random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry
Product features
Magnetic properties
The magnetic properties of the product is featured by its low core loss, high permeability and excellent application performance.
Thickness tolerance
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.
Processing property
The productis suitable for punching and cutting with excellent dimensional tolerance.
Insulation coating
The insulation coating has small color deviation. good adhesiveness and excellent resistance to heating and corrosion with high insulation coating resistance.There are several tvpes of insulation coatina 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.
Different insulation coatings are available to meet a range of customer requirements according to interlaminar resistance.
corrosion resistance. punchability, weldability and so on.

Brand representation
The steel grade comprises the following in the order given:
1)onehundred times the nominal thickness of the material, in millimeters:
2)characteristic letter
Q: capital letter of Chinese Pinyin "Qu":
G: capital letter of Chinese Pinyin "Gao".
RK: domain refined grades by laser scribing, to be deteriorated when
subjected to heat treatment.
3)onehundred times the maximum value of specific total loss in watts per
kilogram at 1.7 T and 50 Hz. unless otherwise specified.
Examples:
Conventional grain oriented electrical steel with the maximum specific total loss of 1.2 W/kg at 1.7Tand 50 Hzand a nominal thickness of 0.30 mm shall be designated as 30Q120.
High permeability grain oriented electrical steel with the maximum specific total loss of 1.2 W/kg at 1.7 Tand 50 Hz and a nominal thickness of 0.30 mm shall be desianated as 300G120.
High permeability grain oriented electrical steel, domain refined by laserscribing, with the maximum specific total loss of 0.90 W/ka at 1.7 Tand 50 Hz and a nominal thickness of 0.27 mm shall be designated as 27RK090.
