High and even hardness;2. Hardness Tolerance: ±2 HRC;3. Very low break rate;4. Perfect, even & deeper quenching effect;5. Microstructure: Tempered martensite, even and small grain.Testing standardDuring Bulk Production, Every 2-3 Hours, Random pick 2-3 Ball Samples to Test Hardness For Recording, Make Sure Even Quality.Our WorkshopQuality control1. 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.
