925

UNS #N09925

925 is an age-hardenable Ni-Fe-Cr alloy designed to resist corrosion while providing high strength. A combination of copper, titanium, molybdenum, and aluminum, in conjunction with nickel, provides excellent resistance to stress-corrosion cracking, pitting and crevice corrosion, and oxidizing and reducing environments.
