Monel 400 is a corrosion-resistant alloy with the largest dosage, the most wide range of uses, and excellent comprehensive properties. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, as well as 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 aside from good cutting performance. Monel 400 bars are commonly adopted in many corrosive applications, particularly in the marine and chemical industries. Monel 400 can be easily machined through conventional machining operations as a relatively soft material suitable for thermoforming into almost any shape.
