China Grain Oriented Electrical Steel Cold Rolled Silicon Steel Sheet for Transformer manufacturers and suppliers

Grain Oriented Electrical Steel Cold Rolled Silicon Steel Sheet for Transformer Featured Image

Short Description:

Electrical steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel, is a material used to produce certain magnetic cores, such as stators and rotors in transformers and motors. Electrical steel is also an indispensable material for the power, electronics and military industries.

Product Detail

Grain-oriented electrical steel usually has a silicon level of 3% (Si:11Fe). It is processed in such a way that the optimal properties are developed in the rolling direction, due to a tight control (proposed by Norman P. Goss) of the crystal orientation relative to the sheet. The magnetic flux density is increased by 30% in the coil rolling direction, although its magnetic saturation is decreased by 5%. It is used for the cores of power and distribution transformers, cold-rolled grain-oriented steel is often abbreviated to CRGO.
