MONEL® ALLOY 400

UNS N04400

Other common names: Alloy 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.

Characteristics

• · 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
• · Excellent resistance to neutral and alkaline salt
• · Good mechanical properties from sub-zero temperatures up to 1020° F

Chemical Composition, %

Corrosion Resistant

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.

Monel 400 offers about the same corrosion resistance as nickel but with higher maximum working pressures and temperatures and at a lower cost due to its superior ability to be machined.

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

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.

Manufacturing Process of Monel Round Bar

Monel round bars are manufactured using different processes, including hot forging, cold forging, and hot rolling. The manufacturing process used depends on the desired size and properties of the round bar.

Hot forging is a process in which the Monel alloy is heated to a high temperature and then shaped into a round bar using a forging press or hammer. Cold forging, on the other hand, involves shaping the Monel alloy at room temperature using a hydraulic press or hammer. Hot rolling is a process in which the Monel alloy is heated and then passed through a series of rollers to produce a round bar with the desired size and properties.

After the round bar is manufactured, it is subjected to various finishing processes, including polishing, grinding, and heat treatment, to improve its surface finish and mechanical properties.
