Product Description

Swaziland Grinding Steel Ball For Mining&Milling

1.Feature:

1) High Hardness: surface hardness of forged steel balls is to 60-68 HRC and volume hardness is to 56-63 HRC

2) High Impact Toughness: impact toughness is more than 12 J/cm2.

3) Low Broken Rate: the actual broken rate is not higher than 1%.

4) Even Wear-resistance: the loss of ball round rate is low.
