Product Feature
Monel 400 has excellent resistance to corrosion by many reducing
media such as sulfuric and hydrochloric acids. It is generally more
resistant 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 point, of
all engineering alloys. Monel 400 is notable for its toughness, it
does not show embrittlement tendency at cryogenic temperatures. It
is work hardenable.
- Monel 400 alloy in the fluoride gas, hydrochloric acid, sulfuric
acid, hydrofluoric acid and their derivatives have a very good
corrosion resistance property, and possess better corrosion
resistance more than the copper alloy in the sea water.
- Acid medium: Monel 400 have corrosion resistance in less than 85%
consistency of sulfuric acid. Monel 400 is an important material
that resistant to hydrofluoric acid.
- Water corrosion: Monel 400 alloy in most corrosion cases of water,
not only excellent corrosion resistance, but also less pitting,
stress corrosion, the corrosion rate less than 0.025mm / a.
- High temperature corrosion: Monel 400 for the work of the highest
temperature at about 600 °C in general in the air, in the high
temperature steam, the corrosion rate less than 0.026mm / a.
- Ammonia: Monel 400 can be resistant to an hydrous ammonia and
aminate conditions corrosion below 585 °Cdue to the high nickel.
