Retension Ring Liners for Cement Mill Hardness More than HRC52
Specification
1.Material:High Cr Cast Iron
2.Hardness:≥HRC52
3.Impact Value:More than AK5J
4.Application:Mining Industry
5.MOQ:2tons
High Cr white iron material possess a combination of superior abrasion resistance and a reasonable
degree of toughness. The high Cr castings have longer service life than the other material,such as
high Mn steel and Cr-Mo alloy steel.And now it is widely used in the working condition of high wear and low impact,such as dry grinding process,coal mills,cement mills due to its excellent performance.
