Hardness is an important mechanical property of materials, but in practical applications, the measured hardness can represent different properties due to different measurements.Static load forcing is usually used for hardness test,there are Brinell hardness, Vickers hardness and Rockwell hardness, and Vickers hardness is much more suitable for hard materials hardness test, such as ceramics.

Corundum, silicon carbide, boron carbide are effective fighting wear come from slag and cement, high molecular polymer and quartz has a very poor abrasion resistance, so they are not suitable to be made into lining materials for vertical mill, roller press, powder selecting machine, powder pipe valves and pipelines, cast steel can be used as a wear resistant liner, but its wear resistance ability would be question.

In short,the development of wear resistant hardfacing materials are based the theory. Super abrasion resistant steel plates and abrasion resistant steel pipe manufactured by Zhangjiagang YaoYu Wear Resistant Materials Company are widely applied to cement and thermal power generation system for its excellent wear resistance and high hardness, and can effectively increase the service life of equipment.
