Electrical steel sheet is a functional material manufactured by modifying the magnetic properties of steel for efficient magnetism and electricity conversion. Losses in power generation, transmission, and consumption are reduced, which contributes to energy saving. As a world leader in developing and commercializing high-grade steel sheet, Nippon Steel & Sumitomo Metal has accumulated a comprehensive skill set in technology and quality, and as such continues to maintain and expand its deep knowledge of steel materials and technology acquired over many years. This heritage plays an essential part in manufacture of the company’s high-efficiency electrical steel, and its ability to satisfy the requirements of the customer, and society in general.
