Description

Special Cast and Forged Grinding Balls

1.Feature:
1) In general, rolling and forged ball is famous for high hardness: surface hardness to 58-68 HRC, volume hardness of 56-63HRC;
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 50-400 g/ton
