Sufficient nickel content in Incoloy Alloy 925 provides protection against chloride-ion stress-corrosion cracking whilst in conjunction with the added molybdenum and copper resistance to reducing chemicals is enjoyed. Molybdenum additionally aids resistance to pitting and crevice corrosion whilst Chromium offers resistance to oxidizing environments. During heat treatment a strengthening reaction is caused by the addition of titanium and aluminium.
Application requiring a combination of high strength and corrosion resistance may consider INCOLOY® 925. Resistance to sulfide stress cracking and stress-corrosion cracking in "sour" crude oil and natural gas environments means that it is used for down-hole and surface gas-well components as well as finding uses in marine and pump shafts or high-strength piping systems.
