Product Description

Product Description

 

Silicon Steel Coils 0.23/0.27/0.30 CRGO Electrical Steel for Transformer Lamination Iron core
Silicon steel, also known as silicon steel sheet or electrical steel, is a very low carbon content ferrosilicon soft magnetic alloy steel, usually containing silicon from 0.5% to 4.5%. The addition of silicon enhances the resistivity and maximum permeability of iron, thereby reducing coercivity, iron loss, and magnetic aging.

The difference between oriented silicon steel and non-oriented silicon steel
Non-oriented silicon steel: A ferrosilicon alloy with very low carbon content. In deformed annealed steel plates, the grains are randomly distributed. The silicon content of the alloy is between 1.5% and 3.0%, or the sum of silicon and aluminum content ranges from 1.8% to 4.0%. These products are usually cold rolled sheets or strips, primarily used in the manufacture of motors and generators.

Superior Quality Grain Oriented Flatrolled Electrical Steel
This premium cold-rolled electrical steel contains between 2.9% to 3.5% silicon (Si) and features a meticulously regular and directional crystal structure. Grain Oriented Electrical Steel is an essential soft magnetic material in the power industry, prominently utilized in transformers, rectifiers, reactors, and large motors, amongst other high-demand applications.
