Description
Alloy 925 (UNS N09925) is an age hardenable nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum, providing a combination of high strength and excellent corrosion resistance. The high nickel content also gives resistance to chloride ion stress-corrosion cracking
It is used in the petroleum industry for applications such as gas well components, valves and tubing, as well as finding use in high-strength piping systems.
