Disclosed is a nickel-base alloy which provides excellent corrosion resistance to a variety of severe environments, especially hot phosphoric acid. The alloy preferably contains, in weight percent: about 30 chromium, about 4 molybdenum, about 2 tungsten, about 1 Cb/Ta, about 1.5 copper, about 14 iro
Disclosed is a nickel-base alloy which provides excellent corrosion resistance to a variety of severe environments, especially hot phosphoric acid. The alloy preferably contains, in weight percent: about 30 chromium, about 4 molybdenum, about 2 tungsten, about 1 Cb/Ta, about 1.5 copper, about 14 iron and the balance nickel plus the impurities and modifying elements usually found in alloy of this class. The alloy is eminently suited for use as articles in chemical processing apparatus in the manufacture and/or containment of phosphoric acid and sulfuric acid.
