Electrical steel is used for core material of electromagnetic devices like transformer and motor, so most important quality of electrical steel is magnetic properties (core loss, magnetic flux density) rather than mechanical strength. Electrical steel is also called silicon steel because it has especially high contents of silicon to improve magnetic properties. Recently the demand of electrical steel is increasing by growth of electrical vehicle market and clean energy system.
