About Alloy 925
What is Alloy 925?
Alloy 925 also referred to as the UNS N09925 alloy.
It is an agehardenable nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum.
Alloy 925 is used in various applications requiring a combination of high strength and corrosion resistance.
Because of the alloy’s resistance to sulfide stress cracking and stress-corrosion cracking in “sour” (H2S containing) crude oil and natural gas, it is used for down-hole and surface gaswell components including tubular products, valves, hangers, landing nipples, tool joints and packers.
The alloy is also used for fasteners, marine and pump shafting and high-strength piping systems.
