Casting high chromium ball for cement
Our Casting steel high chromium balls have following advantages:
Uniform hardness: 60-65HRC
High grinding resistance
Low breakage: below 1%
High impact value
Casting steel high chromium balls we produced are widely used in mining, cement industries.
After years of research and development, a variety of excellent wear-resistant materials have developed and produced by us.
We mainly produce high chrome casting balls from 15mm to 100mm.
We can supply casting balls with High and Low Cr:
