Sandvik Sanicro 31HT Seamless tube and pipe

 

Subcategory: Nickel Alloy; Metal

Close Analogs: UNS N08811, N08810; EN 1.4959

Material Notes:
Sandvik Sanicro 31HT is an austenitic nickel-iron-chromium alloy characterised by:

  • high creep strength
  • very good resistance to oxidation
  • good resistance to combustion gases
  • very good resistance to carburization
  • good resistance to nitrogen absorption
  • good structural stability at high temperatures
  • good weldability

    • Sandvik Sanicro 31HT can be used at temperatures up to about 1100°C (2010°F). In order to have the best ductility, it should be used above 700 °C (1290 °F). We can also supply a modified version of Sandvik Sanicro 31HT for use in the temperature range between about 550 and 700°C (1020-1290°F). The chemical composition and heat treatment of this version have been adapted for the highest possible creep ductility. Further information on properties is available on request.

    Sandvik Sanicro 31HT is not generally used under wet corrosive conditions. For this type of environment, we recommend Sandvik Sanicro 30, which is specially adapted for wet corrosive conditions up to about 550°C (1020°F). For further details, see the Sandvik Sanicro 30 datasheet on our website (www.smt.sandvik.com) or in printed form (S-1890-ENG).
