Monel 400｜Alloy 400｜ N04400｜Pipe and Tube
Monel 400 (Alloyl 400, UNS N04400/W.Nr. 2.4360 and 2.4361) is a nickel-copper alloy (about 67% Ni – 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Monel 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good corrosion resistance, good weld-ability and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwater, 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 hydro-chloric and hydro-fluoric acids when they are deaerated. As would be expected from its high copper content, alloy 400 is rapidly attacked by nitric acid and ammonia systems.
