INCONEL alloy 690 (UNS N06690/W. Nr. 2.4642) is a high-chromium
nickel alloy having excellent resistance to many corrosive aqueous
media and hightemperature atmospheres. In addition to its corrosion
resistance, alloy 690 has high strength, good metallurgical
stability, and favorable fabrication characteristics.The chemical
composition of INCONEL alloy 690 is listed in Table 1. The
substantial chromium content gives the alloy outstanding resistance
to oxidizing chemicals and to high-temperature oxidizing gases.
The high level of nickel imparts resistance to stresscorrosion
cracking in chloride-containing environments as well as to sodium
hydroxide solutions.The properties of INCONEL alloy 690 are useful
for various applications involving nitric or nitric/hydrofluoric
acid solutions. Examples are tail-gas reheaters used in nitric acid
production and heating coils and tanks for nitric/hydrofluoric
solutions used in pickling of stainless steels and reprocessing of
nuclear fuels.
The alloy’s resistance to sulfur-containing gases makes it an
attractive material for such applications as coal-gasification
units, burners and ducts for processing sulfuric acid, furnaces for
petrochemical processing, recuperators, incinerators, and glass
vitrification equipment for radioactive waste disposal.
