Specifications

Forged Grinding Steel Ball

1.Feature:

1) In general, grinding steel ball has high hardness: surface hardness to 55-68 HRC, volume hardness of 50-63 HRC

2) impact toughness high: impact toughness more than 12 J / cm2.

3) broken rate is low: the actual broken rate is not higher than 1%.

4) loss of grinding forged steel ball round rate is low.
