1 High chromium cast iron

The performance of high Cr balls in secondary grinding depends on the abrasive/corrosive environment of the mill. In most secondary Au, Cu, and Mo grinding, the relative wear rates of high Cr compared to forged steel show a performance improvement of 25 – 30%, similar to that seen in primary grinding.
