Ball mill grinding steel rolling ball

Our hot rolling steel ball size from 20mm to 80mm, have precise size, round geometry, high hardness and good mechanical properties, and have excellent quality of wear resistance, no deformation and low cracking. Its characteristics are as follows:

1. High overall hardness: the surface hardness can reach 60-65hrc, the volume hardness can reach 60-65hrc, and the hardness gradient distribution is uniform.

2. High impact toughness: the impact toughness is greater than 12j / cm2;  

3. The actual breaking rate is not more than 1%.
