UNS N04400
Monel 400 has a wonderful corrosion resistance by many reducing media such as sulfuric and hydrochloric acids. Generally, Monel 400 has a more resistantance to corrosion by oxidizing media than higher copper alloys. Monel 400 resists pitting and stress corrosion cracking in most fresh and industrial waters. It has good resistance in flowing seawater, but under stagnant conditions, pitting and crevice corrosion is induced. Monel 400 is probably the most resistant to hydrofluoric acid in all concentrations up to the boiling points. Monel 400 is not able for its toughness, it does not show embrittlement tendency at cryogenic temperatures. It is work hardenable.
Applications:
Monel 400 is applied in these field, like Chemical process equipment, crude oil stills, gasoline and fresh water tanks, marine engineering equipment, valves, pumps and fasteners.
