- Detail
- Parameters
Chrome alloyed casting iron is divided into three types: high chrome alloyed casting iron(with the chromium content at 8-26%, the carbon content at 2.0-3.6%), medium chrome alloyed casting iron(with the chromium content at 4-6%, the carbon content at 2.0-3.2%), low chrome alloyed casting iron(with the chromium content at 1-3%, the carbon content at 2.1-3.6%). Its distinctive features is that the M7C3 type eutectic carbide micro hardness is HV1300-1800. The eutectic carbide is distributed on the base, martensite (the most hard metal matrix organization), in discontinuous network and isolation, which reduces the fragmentation of the matrix effect. As a result, the high chromium ball mill liner has high strength, strong toughness and good wear resistance performance, which represents the highest level of metal wear resistant materials.
