Monel 400 is a corrosion-resistant alloy with the largest usage, the widest range of uses, and excellent comprehensive properties. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, and also has excellent corrosion resistance against hot concentrated alkali liquid. It is also resistant to corrosion from neutral solutions, water, seawater, atmosphere, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracking and has good cutting performance. Monel 400 pipe is widely used in many corrosive applications, particularly in the marine and chemical industries. Monel 400 can be easily machined through conventional machining operations.
