Non Oriented Electrical Steel 
50W470 is a widely adopted grade of non-oriented silicon steel (CRNGO electrical steel), known for its grate balance of performance and value. It is engineered for reliability and low core loss, making it a cost-effective choice for many applications.
You can find this versatile material in the form of coils, sheets, or slit coils, used in industrial motor stators, generator cores and common home appliance compressors.
