According to the different production processes, electrical steel is divided into two types: hot-rolled and cold-rolled. Cold-rolled electrical steel is divided into oriented electrical steel and non-oriented electrical steel according to the internal grain orientation.
The grain orientation of electrical steel is basically in one direction, with high silicon content, mainly used in transformer manufacturing; non-oriented electrical steel grain distribution is disordered, with low silicon content, mainly used in motor manufacturing.
Non-oriented electrical steel can be used for motors, etc., which are the core components of electric vehicles. Special treatment to make the steel magnetic requires sophisticated production technology such as impurity removal. This steel is indispensable for the efficient drive of motors and directly affects energy-saving performance such as range.

Future Scope of CRGO Silicon Steel
While there have been alternatives to the CRGO grades of steel such as nickel-iron, mu-metal, amorphous boron strip, superglass etc still CRGO steel is the superior choice in the transformer industry. Alloys like the amorphous metal Fe78-B13-Si9 has shown to have much lesser core losses when used as the core of distribution transformer as compared to the CRGO grade steel. An optimum constituent of silicon addition in steel can change the texture so as to achieve desirable magnetic properties when manufactured under controlled conditions.
