  Incoloy 800HT/UNS N08811

  Density: 8.0g/cm3

  Alloy 800HT (UNS N08811) is an austenitic high-strength solid-solution Ni-Fe-Cr alloy with controlled levels of carbon, aluminium, titanium, silicon and manganese and increased content of (Al+Ti).

 

   A special solution treatment gives highest creep-rupture strength above 700°C (1290°F) due to the precipitation of TiC.

2)Characteristic of Incoloy 800HT

· Excellent creep strength at temperature above 700°C (1290°F)

· Good resistance to reducing, oxidising and nitriding atmospheres and to atmospheres which alternate between reducing and oxidising conditions

· Metallurgical stability in long-term application at high temperatures

Where frequent excursions to temperatures lower than 700°C (1290°F) during service cannot be excluded or parts of the material with run permanently at a regime below 700°C (1290°F) the use of alloy 800H is recommended.
