Inconel 690 Special Alloy UNS N06690 High-Temperature Alloy Used In Production Of Nitric Acid And Steam-Heating Coils

Product Description

Inconel Alloy 690 (UNS designation N06690) is a high-chromium nickel alloy with excellent resistance to many corrosive aqueous media and high-temperature atmospheres. The alloy' s high chromium content gives it excellent resistance to aqueous corrosion by oxidizing acids (especially nitric acid) and salts, and to sulfidation at high-temperatures.

APPLICATIONS

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 high-temperature service in gases containing sulfur.
