added to supplement the Cr content, particularly in balls of larger diameter. A high C content (i.e. >0.85%) in the forged steel balls leads to a reduction in toughness, which usually causes spalling of grinding balls. This is due to an increased tendency to retained austenite in high carbon steels8. The manufacturer's test report.
