This material is kind of wear-resistant Nickel-base alloy for hard surfacing which can be substituted for Cobalt-base alloy. The new alloy is mainly comprised of C, Si, Cr, W and Cu and is of a low carbon, high chromium, high silicon, high tungsten and copper type Ni-base alloy. The said Ni-base alloy has excellent high temperature adhesive wear resistance and intercrystalline corrosion resistance properties, which are superior to that of the stellite No. 6 alloy Co-base alloy. In addition, the hardness, abrasive wear resistance, scratch resistance, corrosion resistance, elevated temperature oxidation resistance, heat resistance fatigue, crack resistance, operational applicability and other properties are equal to that of Stellite No. 6 Co-base alloy. The alloy of this invention can be used as a substitute for Co-base alloy in hard surfacing of high temperature, high pressure valves and valves for nuclear industry as well as other easily worn spare parts.
