Alloy 925 / Incoloy 925 / UNS N09925 is an age hardenable nickel-iron-chromium alloy with the addition of molybdenum, copper, titanium and aluminium. Each of these additions play their own part in making Alloy 925 a high strength alloy with excellent corrosion resistance. Alloy 925 is used in various applications in the crude oil and natural gas industry this is because Alloy 925 is resistant to sulfide stress cracking and stress-corrosion cracking and therefore a perfect alloy for use down-hole and surface gas well components.
