GNEE Steel Oriented Electrical Steel
Grain-oriented silicon steel refers to cold-rolled electrical steel containing 2.9%~3.5%i, and the crystal structure of the steel plate has certain rules and directions. It generally refers to a single-oriented silicon steel sheet with a Gaussian texture, that is, a silicon steel whose crystal plane is parallel to the rolling surface and whose crystal orientation is parallel to the rolling direction. There is also a cold-rolled dual-oriented (cubic texture 1003<001>) silicon steel.

Grain oriented silicon steel advantages
Electrical steel, also known as silicon steel or transformer steel, is a specialized type of steel that has been used in a variety of electrical applications over the years. It has many properties that make it an ideal material for the production of transformers, electric motors and other electrical engineering components. In this blog post, we will learn about the properties of oriented electrical steel, which has many advantages over other types of electrical steel. The main advantage is that it has a very high magnetic flux density. This means it can carry more current than other types of electrical steel and therefore be more efficient. It also has very low hysteresis losses, meaning it loses less energy when the magnetic field changes direction. This makes it more efficient overall. Finally, oriented electrical steel is very corrosion resistant and therefore lasts longer.
