Non Oriented Electrical Steel 
Non oriented electrical steel is a silicon iron soft magnetic alloy with very low carbon content, and is an indispensable and important material in power, electronics, and military industries. With the development of high-speed and miniaturization of motors, higher requirements have been put forward for the performance of non oriented silicon steel, such as low iron loss and high magnetic induction strength at high frequencies.
