Material Description UNS N09925 Chemical Composition, %
Incoloy alloy 925 is a nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum. It has the combination of high strength and excellent corrosion resistance. The nickel content is sufficient for protection against chloride-ion stress corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing chemicals. The molybdenum aids resistance to pitting and crevice corrosion. The alloy’s chromium content provides resistance to oxidizing environments. The titanium and aluminum additions cause a strengthening reaction during heat treatment. |
● A high level of corrosion resistance
● In both reducing and oxidizing environments, it has a general corrosion resistance, pitting, crevice corrosion, inter-granular corrosion and stress-corrosion cracking
● Particularly useful for the environments of crude oil and natural gas, sulfuric acid, phosphoric acid, and seawater
● Good resistance to stress-corrosion cracking in a sour environment at high pressure and temperature.
● Good resistance to sulfide stress cracking, a form of hydrogen embrittlement.
Application
● Sulfide stress cracking and stress-corrosion cracking in “sour” (H2S containing) crude oil and natural gas.
● Tubing for Down-hole and surface gas well
● High-strength tubing system
