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.
