Abstract
A process for heat treating alloy objects which comprises solution treating a nickel-base alloy containing chromium, molybdenum, copper, titanium, aluminum and iron at a temperature in excess of 955.degree. C. and then aging the alloy without intervening cold work at a temperature in the range of 700.degree. C. to 720.degree. C. This treatment provides non-cold worked structure which is tough, not susceptible to stress corrosion cracking in a test environment simulating a sour gas well environment and which exhibits high level of fracture energy in a slow strain rate tensile test in that environment.
