CGO Grain Oriented Electrical Steel M3/M4/M5/M6 Product Description
Grain-oriented electrical steel usually has a silicon level of 3%. 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.
We produce cold rolled grain oriented plates (CRGO), also known as transformer plates. They are made of 3% silicon steel. Contains four levels of CRGO sheets:
