B35A270 is a high-efficiency non-oriented electrical steel produced by Baosteel, with a thickness of 0.35mm and a guaranteed maximum iron loss of 2.70 W/kg (P₁.₅/₅₀). Its high magnetic induction enables effective power transmission, while its low core loss enhances energy efficiency. Typically supplied as cold-rolled coils or strips, it is widely used in high-performance applications such as large and medium-sized generators and electric vehicle motors.
