General Description
Incoloy 925 (UNS N09925) is an agehardenable nickel based alloy with additions of molybdenum, copper, titanium and aluminum. Alloy 925 offers corrosion resistance comparable with that of alloy 825, but with higher strength obtained by age hardening. The combination of nickel and chromium renders protection in both oxidizing and reducing atmospheres. The high nickel content also gives resistance to chloride ion stress-corrosion cracking. Pitting and crevice corrosion resistance is also excellent.
