Forged Steel Ball grinding media 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 usual hardness: the floor hardness can attain 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 overall performance is more than 10 instances that of everyday solid metallic balls, the real breaking price isn't greater than 1%.
