Product Description

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.
