Product Detail

Product Description

WC-Cr3C2-Ni is a tungsten carbide based coated powder with high hardness. It adopts agglomeration sintering process. Compared with other WC based powders, WC-Cr3C2-Ni has better oxidation resistance and corrosion resistance, better chemical resistance, excellent carbide dispersion promotes better microstructure, better deposition efficiency and density, and smoother coating. 73WC-20Cr3C2-7Ni powder is widely used in oil & gas, chemical industry valve, pump block, sealing ring, and paper making area etc.
