Monel 400 Round Bars UNS No 4400

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.

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
  • Good mechanical properties from sub-zero temperatures up to 1020° F
  • High resistance to alkalis

Corrosion Resistant Monel 400

· Alloy 400 is virtually immune to chloride ion stress corrosion cracking in typical environments. Generally, its corrosion resistance is very good in reducing environments, but poor in oxidizing conditions. It is not useful in oxidizing acids, such as nitric acid and nitrous. Nevertheless, it is resistant to most alkalis, salts, waters, food products, organic substances and atmospheric conditions at normal and elevated temperatures.

Applications of Monel 400

  • Marine engineering
  • Chemical and hydrocarbon processing equipment
  • Crude petroleum stills
  • Boiler feed water heaters and other heat exchangers
  • Valves, pumps, shafts, fittings, and fasteners
  • Industrial heat exchangers

Monel® Alloy 400

UNS N04400 

Common Trade Names: Monel 400, Alloy 400; Nickel 400; Nickelvac 400; Nicorros 400.

Monel® Alloy nickel-copper alloy 400 (UNS N04400; W.Nr. 2.4360 and 2.4361) is a solid-solution alloy that can be hardened only by cold working. It has high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments.

Alloy 400 is widely used in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and fresh water tanks; crude petroleum stills, process vessels and piping; boiler feed water heaters and other heat exchangers; and deaerating heaters.

Nickel Alloy 400 and Monel® 400, also known as UNS N04400, is a ductile, nickel-copper based alloy comprised essentially of two-thirds nickel and one third copper. Nickel Alloy 400 is known for resistance to a variety of corrosive conditions, including alkalies (or acid like substances), saltwater, hydrofluoric acid and sulfuric acid. Other advantages of using this alloy are its toughness and high strength over a broad temperature range; it can also be manipulated to become magnetic if desired. Fortunately, if Nickel Alloy 400 doesn’t meet your specific needs, NSA stocks other nickel-copper based alloys to choose from.

Industries that use 400 include:
Chemical, Marine, Electronic and electrical components.Fresh water and gasoline tanks, Heat exchangers,Marine hardware and fixtures, Process piping and vessels,Propeller shafts,Pumps,Pump shafts,Springs,Valves.

Applications of Monel 400

  • 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

Fabrication with Monel 400

Alloy 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 be obtained if you make the correct choices for tooling and machining.
