Alloy 825 (Inconel® 825)

Nickel Iron Chromium Alloy

Alloy 825 Nickel Alloy

Alloy 825 is a nickel iron-chromium alloy which has been developed to provide exceptional resistance to numerous corrosive environments including both oxidation and reducing.

Corrosive Environments

These environments include sulphuric, sulphurous, phosphoric, nitric, hydrofluoric and organic acids and alkalis such as sodium or potassium hydroxide, and acidic chloride solutions. Alloy 825 also offers outstanding performance in subsea applications.


Alloy 825 is a nickel alloy which readily formable and weldable with superb resistance to chloride stress corrosion cracking. It is, therefore, an outstanding subsea performing alloy with excellent resistance to reducing and oxidizing acids, and pitting and crevice corrosion.

Typical Applications

Commercial applications for this engineering material include:

  • Evaporators
  • Seawater heat exchangers
  • Air-cooled heat exchangers
  • Sour gas components
  • Chemical processing equipment
  • Air pollution scrubbers
  • Pipe systems
  • Ore processing

We stock Alloy 825 in round bar, plate and sheet.
