Inconel 690 (UNS N06690 ALLOY 690) Seamless Nickel Alloy Pipe
General Description
Inconel 690 has the highest chromium content (29% Cr) among nickel
alloys suitable for fabrication of pressure equipment, which
confers exceptional resistance to oxidizing media. It is used for
hot sulfuric acid, nitric acid, and nitric/ hydrofluoric acid
mixtures, as well as for oxidizing salts. The high chromium content
also improves resistance in hot sulfidizing environments.
Inconel 690 has good resistance to oxidizing chemicals, such as
nitric acid, and to sulfur-containing gases at high temperature.
Inconel 690 has a superior stress cracking resistance than Inconel
600 in steam generation nuclear reactors for piping, separators and
weldments.
Applications involving nitric acid or nitric-plus-hydrochloric
acid. Examples are tail-gas reheaters used in production of nitric
acid and steam-heating coils in nitric- plus-hydrochloric acid
solutions used for pickling stainless steels and reprocessing
nuclear fuels. Inconel 690 is also useful for hightemperature
service in gases containing sulfur.
