Abstract: A process and an alloy are provided for producing high strength material having good ductility to provide a high strength, corrosion resistant alloy including the steps of (1) preparing a body of material having a composition consisting essentially of by weight, about 13% to 18% chromium, about 13% to 18% molybdenum, less than 0.01% carbon, less than about 6% iron, less than about 1.25% cobalt, less than about 4% tungsten, less than 0.5% aluminum, less than 1% manganese, less than 0.5% silicon, and the balance nickel with usual transient metals and impurities in ordinary amounts, and (2) thereafter aging said body at a temperature in the range about 900.degree. and 1100.degree. F to effect an A.sub.2 B ordering reaction in the composition.

Abstract: A nickel-base alloy is provided having excellent corrosion resistance to both oxidizing and reducing environments in all of the annealed, welded and thermally aged conditions. The alloy has the broad composition:______________________________________ Chromium 12-18 Molybdenum 10-18 Iron 0-3 Tungsten 0-7 Aluminum <0.5 Carbon 0.02 max. Silicon 0.08 max. Cobalt <2 Manganese <0.5 One of the group Titanium, up to 0.
