Non-oriented electrical steel
Non-oriented electrical steel (NOES) has high permeability, high magnetization saturation, low core loss, and relatively low cost.
The magnetic properties of non-oriented electrical steels strongly depend on the silicon content, the cleanliness of the steel, the thickness of the steel sheet, and the grain size and texture of the final lamination.
Non-oriented electrical steel, often referred to as non-grain-oriented electrical steel or simply non-oriented steel, is a type of soft magnetic material used in the construction of electrical machines and devices. It is an essential component in the manufacturing of motors, generators, transformers, and other electromagnetic devices that require efficient and low-loss magnetic properties.

Characteristics
Magnetic Properties
The magnetic properties of the product are featured by its low core loss, high permeability, and excellent application performance.
Thickness Tolerance
Good thickness tolerance is characterized by a small difference in thickness in a direction parallel to the direction of rolling, a small difference in thickness in a direction perpendicular to the direction of rolling, and a high lamination factor.
Processing Properties
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 environmental 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, punch ability, weldability, and so on.

Note:
1. Unless otherwise specified, the surface coating for non-oriented electrical steel is designated as T4 coating.
2. The self-bonding surface coating is designated as Z coating. Following the procedures of stamping and stacking, the laminations with Z coating will be adhered to by themselves after the treatment of hot pressing to assure the overall strength of the iron core. The procedure of welding or riveting is not necessary. It must be emphasized that the electrical steel strip and sheet with self-bonding coating shall be used within six months after ex-works.
