Monel 400 is a nickel-copper alloy (about 23% Cu–67% Ni ) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good weldability, good corrosion resistance and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. This nickel alloy is particularly resistant to hydrofluoric and hydrochloric acids when they are de-aerated. As would be expected from its high copper content, alloy 400 is rapidly attacked by nitric acid and ammonia systems.

Monel 400® is a nickel-copper alloy that is hardened by cold working only. Monel 400® has low corrosion rate in flowing seawater, therefore it is widely used in marine applications. Monel 400® also has excellent resistance to stress corrosion cracking in most freshwaters. Monel 400® can be used in temperatures up to 1000 º F. The alloy has great mechanical properties at subzero temperatures.

Available forms are Monel 400 Seamless Pipe, Monel 400 Welded Pipe, Monel 400 Seamless Tube, Monel 400 Welded Tube, Monel 400 Round Bars, Monel 400 Wire, Monel 400 Sheet, Monel 400 Plate, Monel 400 Forgings, Monel 400 Pipe Fittings and Monel 400 Flanges.
