Cold rolled steel coil/plate manufacturers and factory in china

The non-grain oriented electrical steel has a different, non-uniform crystal orientation. Its main applications include products containing rotating parts, such as motors and generators. Grain oriented electrical steel has a uniform crystal orientation, featuring a much higher magnetic performance. Its main applications include products that have a stationary phase, such as transformers. Demand for electrical steel is increasing as the need for clean energy sources is rising to save energy and prevent environmental pollution.

GRAIN ORIENTED AND NON-GRAIN ORIENTED STEEL

Grain Oriented Electrical Steel

Grain-oriented electrical steels (GOES) are alloyed with iron and silicon, and are developed to provide low core loss and high permeability.

During the development of GOES, the material is processed with optimal magnetic properties developed in direction that it is rolled in. The overall magnetic flux density of grain-oriented material is increased by 30% in the direction that it’s rolled in, but its magnetic saturation is reduced somewhat. GOES is most commonly used in high-efficiency transformers, generators, and motors.

Cold Rolled Grain-Oriented Steel is abbreviated as CRGO.

Non-Grain Oriented Steel

Non-grain-oriented steel is electrical steel that is NOT cold rolled in a specific direction to control its crystal orientation. It usually has a silicon level of 2 to 3.5%, and magnetic properties that are consistent in all directions. Its benefit lies in the fact that it’s far cheaper to produce, and is most applicable when lowering costs is more important than increasing efficiency, which is often the case in motors and other appliances without a magnetic flux.

Cold rolled, non-grain-oriented steel is abbreviated as CRNGO.
