With the continuous development of mining machinery equipment, wear-resistant materials has become an indispensable part for each part of the mining machinery equipment, such as mill lining plate, jaw plate,hammer, vertical mill and other consumable parts. Now the wear-resistant materials have been developed to the third generation.

High manganese steel is known as the first generation of wear-resistant materials and was produced in 1882. It was used in large crushing equipment, it is extremely tough, and became hardening in strong shock conditions. However, it is not suitable for low impact load or low stress.

The second generation of wear resistant materials is Ni hard cast iron and appeared after 1930. We added 3-5% Ni and 1.5- 3.5% Cr to ordinary white cast iron, and mainly applied to vertical mill. It has high hardness, good wear resistance, but the low hardness and toughness and high cost, so it has gradually withdrawn from wear resistant materials market.

The third generation of wear-resistant material is high chromium cast iron and alloy steel. High chromium cast iron is an excellent performance, can be used as small and medium sized mill lining plate, small hammer crusher, wear resistance performance is better than alloy steel and has strong toughness than white iron, high temperature resistance and corrosion resistance.

chromium carbide wear resistant steel plate can be used as liner plate and screen plate in mining, coal - washing factory and sand factory.
