Monel 400/N04400 Nickel Alloy Pipe/Tube

Monel N04400 Alloy is a Nickel-Copper alloy that is resistant to seawater and steam at high temperatures as well as to salt and caustic solutions. Monel alloy 400 is a solid solution alloy that can only be hardened by cold working. The Monel 400 pipe using nickel alloy 400 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 freshwater, and the resistance of Monel alloy 400 seamless pipe to a variety of corrosive conditions led to its wide use in marine application and other non-oxidizing chloride solutions. 

As one of the pro Monel 400 pipe tubing suppliers in China, Yuhong Group provides quality alloy 400 tubing solutions for you. Feel free to contact at any time.

Monel 400/N04400 Alloy Pipe/Tube Highlights

ASME SB 163 SB 165 ASTM B163 B165 N04400 Monel 400 Alloy 2.4360 Alloy is particularly resistant to hydrochloric acid and hydrofluoric acid when they are de-aerated. As would be expected from its high copper content, Monel 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, Monel 400 pipe is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.
