INCOLOY 800/800H/800HT-----Sheet/Strips/Coil


Incoloy alloy has many types: common Incoloy800, Incoloy800H, Incoloy800HT, Incoloy825, Incoloy840, Incoloy901, Incoloy925, Incoloy20, Incoloy330, Incoloy 25 to 6 mo, etc.Here, I introduce two of the most common material Incoloy800 (800 h, 800 ht) and Incoloy825


Alloys 800, 800H and 800HT have the same nickel, chromium, and iron contents and generally display similar corrosion resistance. The high nickel and chromium contents of Incoloy 800H, 800HT and 800 ensure excellent resistance to oxidation.Compared to Incoloy 800,the 800H and 800HT can be used at higher temperature and still have a good strenth,the alloys are also very resistant to carburization, nitridation and oxidizing sulphur-bearing atmospheres at high temperature.Resistance to hydrogen is excellent for Incoloy 800H and 800HT.


  • Incoloy 800H:
    Good creep-rupture properties at temperatures above 600 °C (1110 °F) without loss of ductility during long-term
    use at temperatures below 700 °C (1290 °F), due to limitation of (Ti + Al) content to max. 0.7 %;
    Good resistance to reducing, oxidizing and nitriding atmospheres and to atmospheres which alternate between reducing and oxidizing conditions;
    Metallurgical stability in long-term application at high temperatures.


  • Incoloy 800HT:
    Excellent creep strength at temperature above 700℃ .However, for applications where frequent excursions to temperatures lower than 700℃ during service cannot be excluded or parts of the material are permanently exposed to a temperature below 700℃, the use of Incoloy 800H is recommended.
    Good resistance to reducing, oxidizing and nitriding atmospheres and to atmospheres which alternate between reducing and oxidizing conditions;
    Metallurgical stability in long-term application at high temperatures.
