Silicon steel sheets are divided into oriented silicon steel sheets and non oriented silicon steel sheets. In terms of chemical composition, the silicon content of oriented silicon steel is higher than that of non oriented silicon steel, and the price of oriented silicon steel sheets is also higher.

Oriented silicon steel is mainly used for transformers, while non oriented silicon steel is mainly used for motors. Silicon steel sheets have good punching properties. This is very important for making small and micro motor iron cores. The newly stamped silicon steel sheet iron core has a bright and non mottled cross-section, and can be directly sprayed with silicon steel rust proof oil before being sealed and packaged. And oriented silicon steel generally has a very good external coating, and under normal circumstances, rusting is relatively rare. If there is rust, it is also formed after edge cutting. If it is a cut silicon steel sheet, it is necessary to clean the surface first before applying rust proof oil to the silicon steel sheet.

Non oriented semi process silicon steel has no coating on its surface and generally requires bluing treatment. Before bluing, the surface should be cleaned and soaked in anti rust oil to prevent rusting. This type of non oriented semi process silicon steel is generally used in motor or compressor industries.

Hot rolled non oriented silicon steel does not have a coating on the surface, but it has an oxide film and also has anti-corrosion properties. It is not easy to rust in a generally non corrosive dry environment.
