What's the difference between B50A470-H and B50A470-A? Is the material for general testing electrical steel or non oriented silicon steel?
H coating is semi organic thick coating. It has excellent film resistance, corrosion resistance, freon resistance and high resistance. It is suitable for medium and small electrical machines. Equivalent to the A1 coating of Kawasaki iron and the T4 coating of Wuhan Iron and steel company.
A coating is a semi organic thin coating, has excellent workability, corrosion resistance, and high resistance of freon, especially the welding performance, suitable for medium and small household electrical appliances, motor, motor and small transformer core EI, T4 coating and A1 coating is equivalent to the Wuhan Iron Sichuan
The coating of two silicon steel sheets is different. One is H coating and the other is A coating.
