Our company is a professional manufacturer and exporter of Grinding Ball, the main products are Forged Steel Grinding Ball as follows:
1.Feature:
1) In general, forged 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.
