Oriented Electrical Steel (silicon steel coil)

Electrical steel (silicon steel coil) is mainly divided into two categories: grain-oriented electrical 

steel and grain non-oriented electrical steel. The direction of easy magnetization grains of 

oriented electrical steel is distributed along the rolling direction. The rolling direction has excellent 

characteristics such as high magnetic induction, low iron loss and low magnetostriction. At the 

same time, it can also be processed by magnetic domain refinement technology to obtain lower 

iron Loss of performance, widely used in the field of transformer industry. The grain direction of 

non-oriented electrical steel is randomly distributed, and the electromagnetic properties are 

uniform in all directions. It is widely used in the motor industry.

The difference between oriented silicon steel and non-oriented silicon steel Non-oriented silicon 

steel: ferrosilicon alloy with very low carbon content. In the deformed and annealed steel sheet, its 

grains are distributed randomly. The silicon content of the alloy is 1.5% to 3.0%, or the sum of the 

silicon and aluminum content is 1.8% to 4.0%. The products are usually cold-rolled plates or strips, 

which are mainly used to manufacture motors and generators.

Oriented silicon steel: It has strong directionality, the lowest iron loss value in the rolling direction, 

the highest magnetic permeability, and a higher magnetic induction value under a certain 

magnetization field. The silicon content of oriented silicon steel is about 3%. It also requires a low 

content of oxide inclusions in the steel and must contain certain inhibitors (MnS, A1N).

Product Details

Product Advantages

1.Stable performance

2.Excellent processing performance: High precision dimension and excellent mechanical properties 

make it easy to be sheared,punched and stacked by high speed punch machine. It also have good 

welding performance.

3.Excellent performance of Insulating coating: Uniform color, good insulation, high adhesion, excellent 

heat resistance and excellent processing performance

Advantage

Silicon steel with silicon content of 1.0 ~ 4.5% and carbon content less than 0.08% are called silicon 

steels. It has the characteristics of high permeability, low coercivity and high resistivity, so the hysteresis 

loss and eddy current loss are small.Mainly used as magnetic materials in motors, transformers, electrical 

appliances and electrical instruments. In order to meet the needs of punching and shearing, certain 

plasticity is required. In order to improve the magnetic inductive energy and reduce the hysteresis loss, 

the harmful impurity content should be as low as possible, and the plate type should be flat and the 

surface quality should be good.
