ABSTRACT:
A nickel base alloy is provided having excellent hot and cold workability and superior corrosion resistance to a variety of media including deep sour gas well environments and highly corrosive oxidizing environments. The alloy consists essentially of, by weight, about 27 to 33% chromium, about 8 to 12% molybdenum, about 1 to 4% tungsten, and the balance nickel. The alloy may also contain as impurities or as additions, up to about 1.5% iron, up to about 0.15% carbon, up to about 1% aluminum, up to about 1% titanium and up to about 2% columbium.
