RESISTANCE TO STRESS-CORROSION CRACKING IN NICKEL ALLOYS

摘要

Nickel-chromium and nickel-chromium-iron-base alloys having an improved level of resistance to intergranular stress-corrosion cracking when in contact with aerated high-purity water at elevated temperatures. Alloys contain controlled amounts of aluminum, titanium, silicon and carbon. Grain size and alloy hardness correlated to further minimize stress-corrosion attack.
