Monel 400 bar
common name: UNS N04400,W.Nr. 2.4360 and 2.4361
Monel alloy 400 is a nickel-copper alloy, about 67% Ni, 23% Cu. It is a solid-solution alloy that can be hardened only by cold working. It has high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments.
Monel 400 has great mechanical properties at subzero temperatures, can be used in temperatures up to 1000 F degree, and its melting point is 2370-2460 F degree. However, alloy 400 is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.

Corrosion Resistant Monel 400
Alloy 400 is virtually immune to chloride ion stress corrosion cracking in typical environments. Generally, its corrosion resistance is very good in reducing environments, but poor in oxidizing conditions. It is not useful in oxidizing acids, such as nitric acid and nitrous. Nevertheless, it is resistant to most alkalis, salts, waters, food products, organic substances and atmospheric conditions at normal and elevated temperatures.
Applications
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 fresh water tanks; crude petroleum stills, process vessels and piping; boiler feedwater heaters and other heat exchangers; and deaerating heaters.
