Silicon Steel

Silicon steel, also known as electrical steel, lamination steel, or transformer steel, is a ferritic alloy of iron and silicon that have magnetic properties, which make it useful in motors and transformers. This type of steel material contains 0.5%-4.5% silicon in weight with low carbon of less than 0.08%. The addition of silicon (Si) improves the magnetic softness and increases the electrical resistivity of steel. There are two forms of silicon steel: grain-oriented electrical steel(GO) and non-oriented electrical steel(NGO). GO silicon steel can be further subdivided into regular grain-oriented (RGO) and high permeability grain-oriented (HGO) materials. Silicon steel is known for its high permeability and low amounts of core loss, which make it useful in the generation, distribution, and consumption of electricity, such as small to large motors, relays, solenoids, appliances' motors, wind turbines, cores of transformers, EV, and power generator equipment, etc.

Features of electrical steel

1.Thanks to the high permeability, low coercivity, and high resistivity of silicon steel, the hysteresis loss and eddy current loss are small.

2.Silicon steel requires high plasticity, smooth and flat surface, and low harmful inclusion in order to satisfy the process of punching and shearing, improve magnetic induction, and reduce hysteresis loss.

3.At present, the production process of hot-rolled silicon steel has been eliminated in China and replaced with cold-rolled silicon steel. The iron loss performance of the silicon steel that GNEE supply far exceeds the iron loss requirements of the international standards.

GNEE Steel always adheres to "quality goes first". We have a strict quality inspection system with 20+ professional inspectors and various sophisticated testing instruments. We perform various tests, such as punching test, bending test, cross-cut test, writing and erasing test, coating thickness test, etc. Third-party quality tests, such as SGS, BV, CE, etc., are also acceptable. More than that, we have a series of advanced equipment to offer further processing services, such as cutting, slitting, profiling, punching, bending, etc.
