Grinding ball Description:
1) High Hardness: surface hardness of forged and rolling balls is to 60-65 HRC and volume hardness is to 60-63 HRC
2) High Impact Toughness: impact toughness is more than 12 J/cm2;
3) Low Broken Rate: the actual broken rate is not higher than 1%;
4) Even Wear-resistance: the loss of ball round rate is 50-300 g/ton.
Chemical Composition
Based on material, the forged steel balls are defined into 7 brands. And The chemical composition is shown in the following:
