Product Description

Product Description

Electical 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 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 Parameters

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 product is 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 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.

 Different insulation coatings are available to meet a range of customer requirements according to interlaminar resistance, corrosion resistance, punchability, weldability and so on.
