Wear and corrosion resistant nickel-base alloy

A weld rod consisting essentially of a nickel tube with a metallic powder contained within said tube, such that a melt produced therefrom consists essentially of a nickel-base wear and corrosion resistant alloy 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 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 content in said composition,
• the melting point of said alloy being less than about 1350.degree. C. said alloy having a composition such that segregation of said alloy upon changing from the molten to the solid state is substantially inhibited.
