Product Details

Monel 400 (UNS N04400)

Introduction of Monel 400

Monel 400 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. Alloy 400 is a solid solution alloy that can only  be hardened by cold working. 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 freshwaters, 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 hydrochloric and hydrofluoric acids when  they are de-aerated. As would be expected from its high copper content, alloy  400 is rapidly attacked by nitric acid and ammonia systems.

Monel 400 has great mechanical properties at subzero  temperatures, can be used in temperatures up to 1000° F, and 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.
