INCOLOY® alloy 800 (UNS N08800, W. Nr. 1.4876) is a widely used
material for construction of equipment requiring corrosion
resistance, heat resistance, strength, and stability for service up
to 1500°F (816°C). Alloy 800 offers general corrosion resistance to
many aqueous media and, by virtue of its content of nickel, resists
stress corrosion cracking. At elevated temperatures it offers
resistance to oxidation, carburization, and sulfidation along with
rupture and creep strength. For applications requiring greater
resistance to stress rupture and creep, especially at temperatures
above 1500°F (816°C), INCOLOY alloys 800H and 800HT are used.
INCOLOY® alloy 800 is used in a variety of applications involving
exposure to corrosive environments and high temperatures. It is
used for heat-treating equipment such as baskets, trays, and
fixtures. In chemical and petrochemical processing, the alloy is
used for heat exchangers and other piping systems in nitric acid
media especially where resistance to chloride stress-corrosion
cracking is required. In nuclear power plants, it is used for
steam-generator tubing. The alloy is often used in domestic
appliances for sheathing of electric heating elements. In the
production of paper pulp, digester-liquor heaters are often made of
alloy 800. In petroleum processing, the alloy is used for heat
exchangers that air cool the process stream.
