Hot Rolled Steel Ball

Hot rolled steel balls 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 and forged steel balls, the impact times of falling balls are more than 20000, and the actual crushing rate is not more than 1%, which is close to no crushing.
