Product Features

Silicon Steel is a silicon iron alloy with a silicon content of 3%~ 5%. Divided into oriented silicon steel and non-oriented silicon steel, also known as electrical steel, silicon electrical steel, lamination steel, relay steel, or transformer steel is specialty steel with silicon added to it, which improves its electrical resistivity and magnetic properties, and reduces hysteresis loss.

This steel is ideal for various electrical applications where electromagnetic fields are important, such as transformers, magnetic coils, and electrical motors, it is an important soft magnetic alloy which is indispensable for power, electron and military industry.Was once known as "the arts and crafts of steel products"

Grain-oriented electrical steel, with its easy magnetization direction parallel to the rolling direction, has excellent magnetic properties in this direction including low core loss, high permeability, and low magnetostriction, and is widely used in the transformer industry. Further, it can obtain lower core loss by domain refinement treatment.

Meanwhile, non-oriented electrical steel, featured by a random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry.

We have Silicon Steel Coil in Oriented and and non oriented type.

Material are 23Q110, 30Q120, 35Q145, 35WW230, 35WW250, 35WW270.

ASTM 36F145, 36F158, 36F168, 36F180, M80050A.

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).
