Inconel Alloy 690

Common Trade Names: Inconel 690, Alloy 690, Nickel 690.
INCONEL alloy 690 (UNS N06690/W. Nr. 2.4642) is a high-chromium nickel alloy having excellent resistance to many corrosive

aqueous media and high- temperature atmospheres. In addition to its corrosion resistance, alloy 690 has high strength, good

metallurgical stability, and favorable fabrication characteristics.
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 stress- corrosion 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 sulfurcontaining 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.
In various types of high-temperature water, alloy 690 displays low corrosion rates and excellent resistance to stresscorrosion

cracking. Thus, alloy 690 is widely used for steam generator tubes, baffles, tubesheets, and hardware in nuclear power

generation.
