摘要： A nickel-base wear and corrosion resistant alloy is provided containing by weight about 20% to 35% Cr, about 1% to 8% Si, about 1.7% to 3.5% C, 0 to 15% W and the balance essentially at least about 40% nickel, the amount of carbon present in said composition being stoichiometrically related to the chromium content to provide carbides based on the formula M.sub.7 C.sub.3, wherein M comprises essentially chromium, the amount of chromium in said M.sub.7 C.sub.3 compound ranging from about 65% to less than about 100% of the total chromium in said composition, the melting point of said alloy being less than about 1350.degree. C. The alloy has particular use in welding consumables for hard facing, for valve seats, for wear resistant sleeves and bushings (castings) and other uses.
摘要翻译：提供镍基耐磨损和耐腐蚀合金，其包含重量约20％至35％的Cr，约1％至8％的Si，约1.7％至3.5％的C，0至15％的W，余量基本上至少约为 40％的镍，所述组合物中存在的碳的量在化学计量上与铬含量相关，以提供基于式M7C3的碳化物，其中M基本上包含铬，所述M7C3化合物中的铬的量为约65％至小于所述组合物中的总铬的约100％，所述合金的熔点小于约1350℃。该合金特别用于硬面，用于阀座的耐磨套和衬套（铸件）的焊接材料中。和其他用途。
