Monel 400 is a highly popular nickel-copper based alloy with about 67% nickel and 23% copper. Its superior strength and corrosion resistance properties make it very well known in multiple industries. It is greatly resistant to steam as well as seawater and thus its toughness and anti-corrosive properties make it perfect for heavy duty applications in oil refineries. Monel 400 performs exceptionally well in high-temperature regions and is often used for the high tolerance tubing. It shows good ductility and thermal conductivity and works in a range of alkaline and acidic environments. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated.

Monel 400 displays great mechanical properties at subzero temperatures and is suitable for use in temperatures up to 1000° F. A range of products can be made from Monel 400 such as Sheets, Plates, Bars, Wires, Pipes, Tubes and Fittings among others. It is majorly used in Marine engineering, Chemical processing, Hydrocarbon processing equipment, Crude petroleum stills and for making Valves, pumps, shafts, fittings, and fasteners. It is also utilised in manufacturing various heaters including De-aerating heaters, Boiler feed water heaters, and Industrial heat exchangers.
