摘要： Disclosed is a nickel-base alloy typically containing in weight percent, about 2.7 carbon, about 10.5 cobalt, about 27 chromium, about 23 iron, about 10 molybdenum plus tungsten, up to 2.5 maximum tungsten, and the balance nickel and incidental impurities. The alloy is especially suited for use as wear-resistant articles and may be produced in various forms, such as castings, metal powder, tube rod and/or wire and wrought articles. The alloy composition is particularly designed to conserve cobalt and tungsten and yet provide wear-resistant articles comparable to cobalt-base alloys with high tungsten contents.

摘要： A thermally stable, oxidation-resistant nickel-base alloy having good engineering properties for use in mechanical equipment operated at temperatures of up to 1600.degree. F. or higher is provided by maintaining the nickel content above 50% by weight and including as essential elements from about 12 to about 18% chromium, from about 8 to about 18% molybdenum and from about 0.005 to about 0.2% lanthanum by weight. Additional elements may be included in limited amounts provided that the average N.sub.v number of the alloy as defined herein is not substantially above about 2.5 and preferably is below about 2.4.
