Alloy 925 (Inconel® 925 925)

Nickel Iron Chromium Alloy

Alloy 925 Nickel Alloy

Alloy 925 is a precipitation-hardened made from nickel, iron and chromium with additions of aluminium, copper and molybdenum.


The material is suitable for applications where a combination of high strength with excellent corrosion resistance is required. Alloy 925 is used in sour gas applications including down-hole and surface gas and well components due to the material’s resistance to sulphide stress cracking and stress corrosion cracking.


Performance characteristics also include outstanding general corrosion, pitting, crevice corrosion and stress corrosion resistance. Nickel and chromium in the alloy mix promote protection in both reducing and oxidising environments.

Typical Applications

Commercial applications for this engineering material include:

  • Oil production equipment
  • Surface and downhole components
  • Valves and pump shafts
  • Fasteners

We stock Alloy 925 in round bar.
