(UNS No. N0. 5500) 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 Products
includes Pipes, Tubes, Sheets, Plates, Coil, Round Bars, Fasteners, Pipe Fittings. This nickel alloy exhibits characteristics like good corrosion resistance, good weldability and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most fresh water, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions.
Monel 400 product range has great mechanical properties at subzero temperatures and can be used in temperatures up to 1000° F. Its melting point is 2370-2460° F. However, alloy 400 is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.
