Products Description
High Carbon steel Chrome & Mo Cement ball mill liner in general refers to a  kind of casting steel with the chromium content at 4%~6%, the carbon content at 0.8%~1.2%. Its distinctive feature is to adopt multivariate alloy design. It increases carbide content in the medium carbon alloyed steel, through increasing the Cr & Mo content, the strong carbide forming elements, so as to improve its heat-resisting, wear-resisting performance. As a result, its high strength, strong toughness and good wear resistance properties represent the relatively high level of metal wear resistant materials.
The material is widely used for power coal mill ,cement mill .
