Monel 400 (UNS N04400) is a corrosion resistant alloy with wide application and excellent comprehensive performance. Monel 400 has excellent corrosion resistance in hydrofluoric acid and fluorocarbon medium. It is also resistant to corrosion of neutral solution, water, seawater, atmosphere and organic compounds. An important characteristic of this alloy is that it generally does not produce stress corrosion crack and has good cutting performance.
