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 ℃ 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 ℃ due to the high nickel.
