Alloy 276 (UNS N10276)

Nickel Molybdenum Chromium Alloy

Alloy 276 Nickel Alloy

Alloy 276 is a nickel-molybdenum-chromium alloy which includes a small amount of tungsten.


In corrosion-resistant terms, it is one of the most superior products on the market. The material is highly resistant to a wide range of chemicals and gases and is used mainly in oil, gas and chemical production. Alloy 276 has a very low carbon and silicon content.

Corrosion Resistance

Alloy 276 displays excellent corrosion resistance to a wide range of media including general corrosion, stress corrosion cracking and pitting and crevice corrosion in extreme environments. Its resistance to carbide precipitation during welding maintains corrosion resistance in the heat-affected zones of welded joints; this makes the material ideal for use in the fabrication of weldable pressurised vessels for sour gas service. Alloy 276 is particularly resistant to certain acids including, hydrochloric, sulphuric and hydrofluoric, or a combination.

Typical Applications

Commercial applications for this engineering material include:

  • Heat exchangers
  • Pressure vessels
  • Sour gas components
  • Reactor vessels
  • Desulphurisation systems
  • Pumps & valves
  • Incinerators
  • Flanges & fittings

We stock Alloy 276 in round bar, round tube and hollow bar.
