The grinding ball with chromium content ≥10%-14%, HRC ≥58 is popular on current market and also very economic .
High chrome grinding ball issuitable for the industry with high requirement on grinding fine,
and high abrasion .
High chrome grinding ball can increase production, and reduce
consumption obviously in the cement industry.
Good toughness, low abrasion, low broken rate of low chromium alloy
casting; low chromium ball hardness can reach 50-62HRC
