Compared with high chromium balls, medium chromium balls have great advantages in price. It belongs to a kind of wear - resistant material with excellent wear resistance and price balance. Quality index of medium chromium cast ball: chromium content 5. 0% - 8. 0% , carbon content 1. 80% - 3. 60% , impact value AK (> 2. 0J/2), national standard requires chromium ball hardness (HRC) must be more than 47. In order to ensure the quality of chromium ball, high temperature tempering treatment should be used to eliminate stress. Dark black or dark red surface of steel ball is the top grade.
