Specific characteristics of the Forged steel  grinding balls:

1, The overall high hardness: the hardness can reach 55-67HRC, volume hardness reaches 50-63HRC, and the average

 hardness gradient distribution.

2, The impact toughness of high impact toughness than 12J/ cm .

3, Low broken rate: crush resistance is the general casting grinding ball 10 times, ball impact more than 20000 times the

 number, the breakage rate of not more than 1%.

4, No deformation: elliptical deformation of steel ball from the beginning to the end.
