Abstract

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.
