About Monel®Alloy 400

Designated as UNS N04400 or DIN W.Nr. 2.4360 / 2.4361, Monel 400 (also known as “Alloy 400”) is a solid-solution nickel-copper alloy with high strength and excellent resistance in a range of media, including seawater, hydrofluoric acid, sulfuric acid and alkalies. The Alloy 400 is also very resistant to stress-corrosion cracking and pitting corrosion in most fresh and industrial waters.

Alloy 400 is widely used in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and freshwater tanks; crude petroleum stills, process vessels, and piping; boiler feedwater heaters and other heat exchangers; and deaerating heaters.
