Nickel alloy Incoloy 800 800H 800HT 825 925 pipe and tube
INCOLOY alloy 925 (UNS N09925) with the additions of molybdenum,
copper, titanium and aluminium is an age hardenable
nickel-iron-chromium alloy, providing a combination of high
strength and excellent corrosion resistance. Sufficient nickel
content provides protection against chloride-ion stress-corrosion
cracking whilst in conjuncton 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 enviroments. 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 enviromments 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.
