Characteristics
ALLOY800 HT is an austenitic high-strength solid-solution Ni-Fe-Cr Alloy with controlled levels of C, Al, Ti, Si and Mg and increased content of (Al + Ti).
A special solution anneal treatment gives highest creep-rupture strength above 700 �C (1290 �F) due to the precipitation of TiC.
Below 700 �C (1290 �F), gamma prime (??) precipitates combined with loss of ductility.
?excellent creep strength at temperature above 700 �C (1290 �F)
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
For applications where frequent excursions to temperatures lower than 700 �C (1290 �F) during service cannot be excluded or parts of the material are permanently exposed to a temperature below 700 �C (1290 �F), the use of ALLOY800H is recommended.

Corrosion Resistance
The high nickel and chromium contents of Alloy800H/HT ensure excellent resistance to oxidation.
The alloys are also very resistant to carburization, nitridation and oxidizing sulphur-bearing atmospheres.
The protective oxide film which is formed is adherent in both static and cyclic conditions of heating and cooling, and resistance to carburization is enhanced when a thin film of oxide is formed on the alloy through pre-oxidation prior to service.
Resistance to hydrogen is excellent and Alloy800H/HT are standard materials used in the production of hydrogen in steam/hydrocarbon reforming processes.
Applications
Due to high strength during long periods of service and resistance to carburization and nitridation, ALLOY800H/HT have found many applications in steam/hydrocarbon reforming for components such as: pigtails, headers/collectors/manifolds, transfer piping, catalyst tubes (in lowpressure processes) and quench-system piping.
Typical applications are:
? ethylene pyrolysis tubing in convection and radiant sections ? resistance to carburization and good mechanical properties
? ethylene dichloride cracking tubes ? resistance to carburization and to dry hydrogen chloride and chlorine
? cracking tubes used in the production of acetic anhydride and ketene ? high strength, resistance to both carburization and the formation of sigma phase
? components, e.g. heat exchangers, piping systems etc., in coal conversion plants
? steam generator tubing in helium cooled, high temperature reactor systems ? high strength, resistance to helium and to steam
