Grinding media forged steel ball
Our forged steel balls and hot rolling steel ball have precise size, round geometry, high hardness and good mechanical properties, and have excellent quality of wear resistance, no deformation and no cracking. Its characteristics are as follows:
1. High overall hardness: the surface hardness can reach 58-65hrc, the volume hardness can reach 55-62hrc, and the hardness gradient distribution is uniform.
2. High impact toughness: the impact toughness is greater than 12j / cm2;
3. Low crushing rate: the anti stripping and anti crushing performance is more than 10 times that of ordinary cast steel balls, the actual breaking rate is not more than 1%.
Forged steel balls are produced with our advanced forging era and strict control of all components of the heat remedy process maximizes wear performance and effect resistance.
