What are the main materials used in Yuma stamping products?

90% is Baosteel, and the remaining 10% is composed of WISCO, Nippon Steel and other materials. The use of materials is still based on the needs of products.

The materials of the stator and rotor are inconsistent. Why does the rotor use a worse row number than the stator?

In terms of performance, the stator has higher requirements for materials. In meeting the performance requirements, the row number can be reduced and the cost can be reduced

Is the thinner the silicon steel sheet material, the better?

The thinner the product is, the more sheets are used at the same height. It is recommended to comprehensively consider the product performance and cost. Our 0.2-thick materials have been mass produced on step 14, which is not difficult to achieve.

What does the English letter of material brand stand for?

B Baosteel

Coating type

Inorganic coating D has good heat resistance and weldability

Semi organic thin coating a improves the stamping property and has good weldability

Semi organic thick coating h has good punching performance and high interlayer resistance

Chromium free coating K coating does not contain hexavalent chromium and has good weldability. It is generally exported to Europe

Self adhesive coating Z has good post bonding performance and high core fixing strength

Example: b50a470 Baosteel 0.5mm thick semi organic coating has good weldability and iron loss value of 4.7
