Gaincin Machinery is manufacturer and exporter for forged steel grinding balls with forging process in house ,our forged grinding steel balls have the following featurers:

1) High Hardness: Surface hardness of forged steel ball is to 60-68 HRC and volume hardness of forged grinding ball is to 60-65 HRC;
2) High Impact Toughness: The impact toughness is more than 15 J/cm2;
3) Low Broken Rate: The actual broken rate is not higher than 1%;
4) Even Wear-resistance: The wear rate of cast ball is 50-700 g/ton.

2. Chemical Composition of Forged Grinding Ball
Based on steel material, the forged steel balls are defined into 7 brands. And their chemical composition is shown in the following:
Material                 C          Mn          Si        Cr     S&P         V
GC-45#         0.42-0.56 0.50-0.8 0.17-0.37 ≤0.25 ≤0.035 ≤0.035
