Chromium Carbide Hardfacing Welding Overlay Wear Liner refers to the various linings made by wear-resistant steel plates through cutting, bending deformation, drilling, welding and other production processes, such as conveyor linings, coal feeder floor / cyclone separator cone and lining board, wear-resistant blades, etc., wear-resistant life can be increased by more than 15 times than ordinary steel.
Chromium Carbide Hardfacing Welding Overlay Wear Liner the chemical composition of the high wear resistance alloy layer contains 4 to 5% carbon and 25 to 30% chromium.
The volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, and the macro hardness is HRC58 to 63.
The hardness of chromium carbide is HV1400 ~ 1800, which is higher than the hardness of quartz in sandstone HV800 ~ 1200.
Since carbides are distributed vertically in the direction of wear, even when compared with casting alloys of the same composition and hardness, the wear resistance is more than doubled.
