Disclosed is an alloy eminently suited for use as a tubular product in deep, sour gas operations. The alloy has an optimum combination of corrosion resistance, high strength in the cold worked condition and resistance to sulfide stress cracking and stress corrosion cracking. A typical alloy contains, in weight percent, 0.03 carbon, 22 chromium, 36 iron, 3 molybdenum, 1 manganese, 36 nickel, 0.60 silicon, 0.15 nitrogen, up to 3 tungsten and incidental impurities including copper, cobalt, columbium, tantalum and titanium.

Corrosion resistant nickel-iron alloy

A sheet of cobalt-base alloy produced by hot working to gauge a slab of hot consolidated atomized prealloyed powder comprises a dispersion of carbide particles in a solid solution matrix, the particles having an average size less than those of the same alloy produced by casting an ingot and hot working it to gauge.
