What are the characteristics of 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

In what applications is Monel 400 used?

  • Marine engineering
  • Chemical and hydrocarbon processing equipment
  • Gasoline and freshwater tanks
  • Crude petroleum stills
  • De-aerating heaters
  • Boiler feed water heaters and other heat exchangers
  • Valves, pumps, shafts, fittings, and fasteners
  • Industrial heat exchangers
  • Chlorinated solvents
  • Crude oil distillation towers

Fabrication with Monel 400

UNS N04400 Alloy 400Alloy 400 can easily be welded by gas-tungsten arc, gas metal arc or shielded metal arc processes using appropriate filler metals. There is no need for post weld heat treatment, however, thorough cleaning after welding is critical for optimum corrosion resistance, otherwise there is the risk of contamination and embrittlement.
Finished fabrications can be produced to a wide range of mechanical properties when proper control of the amount of hot or cold working and the selection of appropriate thermal treatments is done.
Like most other nickel alloys, Monel 400 is typically tough to machine and will work harden. However, excellent results can e obtained if you make the correct choices for tooling and machining.
