Grain-Oriented Electrical Steel

Grain-Oriented Electrical Steel is an electrical steel in which the easy magnetization direction of the grain is parallel to the rolling direction and the silicon content is about 3%.
●Exhibits excellent magnetic properties in one direction (the rolling direction) of the steel sheet
●Features excellent magnetic properties, including high magnetic flux density, low iron loss, and low magnetostriction
●Typical applications: power transformers, distribution transformers, audio transformers, current and potential transformers, medium to large generators, reactors, and magnetic shields.


Grain-Oriented Electrical Steel Characteristics

❶ Magnetic properties
The magnetic properties of the product is featured by its low core loss, high permeability and excellent application performance.

❷ 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.

❸ Processing property
The product is suitable for punching and cutting with excellent dimensional tolerance.

❹ 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.

a. The traverse thickness deviation refers to the thickness difference between the center of the steel plate and 15mm from the edge.

b. The longitudinal thickness difference is the difference between the maximum thickness and the minimum thickness measured along the length direction (parallel to the rolling direction) on any steel strip with a length of 2m.
