Monel 400 UNS N04400 Bar / Seamless tube/ Wire/ flange

Product Detail

Common Trade Names: Monel alloy 400 ,alloy 400,Monel nickel-copper alloy 400 ,UNS N04400,W.Nr. 2.4360

Monel400  is a nickel-copper solid solution strengthened alloy. The alloy is characterized by moderate strength, good weldability, good general corrosion resistance and toughness. It is useful at temperatures up to 1000°F (538°C). Alloy 400 has excellent resistance to rapidly flowing brackish or seawater where cavitation and erosion resistance is necessary. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. Alloy 400 is slightly magnetic at room temperature.

Why Monel 400 ?

Resistant to seawater and steam at high temperatures
Excellent resistance to rapidly flowing brackish water or seawater
Excellent resistance to stress corrosion cracking in most freshwaters
Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated
Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids
Excellent resistance to neutral and alkaline salt
Resistance to chloride induced stress corrosion cracking
Good mechanical properties from sub-zero temperatures up to 1020° F
High resistance to alkalis
