Incoloy800 Alloy 800 is widely used in equipment that must have
high strength and resistance to oxidation, carburisation and other
harmful effects of high temperature exposure. For service requiring
optimum creep and rupture properties, Incoloy 800H or 800 HT are
used. The high contents of nickel and chromium in the alloys also
give good corrosion resistance.

Incoloy 800 is a solid solution strengthened alloy of nickel,
chromium and iron with small additions of aluminium and titanium.
Incoloy 800H and Incoloy 800HT are developments of Incoloy 800,
which give better performance at high temperature. ASME design
codes give significantly higher design strengths for Incoloy H and
HT than Incoloy 800, and allow their use to higher temperatures.
AS1210 prequalifies Incoloy 800 for use to 800°C. ASME
specifications allow the use of Incoloy 800 to 815°C, and of
Incoloy 800H and 800HT to 982°C.
Typical Applications
Thermal processing equipment in industrial applications, such as
baskets, trays, and fixtures. In chemical or petrochemical
processing it is used for heat exchangers and piping systems in
nitric acid media, especially where resistance to chloride stress
corrosion cracking is required.
Description
Incoloy 800/800H/800HT are solid solution nickel chromium iron
alloys with small additions of aluminium and titanium to improve
corrosion and oxidation resistance. They are used for high
temperature service, where resistance to oxidation and
carburisation are required. For optimum stress rupture properties,
or for pressure vessel service above 815°C, Incoloy 800H or Incoloy
800HT should be used.
Availability
Austral Wright Metals can supply these alloys as plate, sheet and
strip, rod and bar, seamless and welded tube and pipe, fittings,
condenser & heat exchanger tube, forgings and forging stock.
