Quality control

1. Only choose Chinese local top brand steel mill as our raw meterial supplier; 

2. Random check raw meterial quality before acceptence to our warehouse;

3. Test production to confirm the production method;

4. Hardness testing; 

5. Confirm the bulk production method based on different ball size to match contract demands;

6. Follow on every production step, from steel rod heating, rolling, cooling, quenching, tempering, focus on all related temperatures, time, etc to promise bulk even quality.
