Monel® 400 - UNS N04400 - EN 2.4360 - Nickel Alloy 400 - NiCu Alloy

As a nickel-copper alloy, alloy 400 has excellent corrosion resistance in a wide variety of media. This alloy is highly resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is characterized by its general corrosion resistance, good weldability, and moderate to high strength in the tempered conditions.

This alloy has excellent resistance to rapidly flowing and warm seawater, brackish water, and steam. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. This alloy is slightly magnetic at room temperature. Alloy 400 is widely used in the chemical, oil, and marine engineering industries.

Applications

Feed water and steam generator tubing.

Brine heaters, sea water scrubbers in tanker inert gas systems.

Sulfuric acid and hydrofluoric acid alkylation plants.

Pickling bath heating coils.

Heat exchangers in a variety of industries.

Transfer piping from oil refinery crude columns.

Plant for the refining of uranium and isotope separation in the production of nuclear fuel.

Pumps and valves used in the manufacture of perchlorethylene, chlorinated plastics.

Monoethanolamine (MEA) reboiling tube.

Cladding for the upper areas of oil refinery crude columns.

Propeller and pump shafts.

Alloy 400 displays strong corrosion resistance in an extensive range of marine and chemical environments, including those containing pure water, nonoxidizing mineral acids, salts and alkalis.

This alloy is more resistant than pure nickel under reducing conditions and more resistant than pure copper under oxidizing conditions.

Alloy 400 displays good mechanical properties - even in environments with subzero temperatures up to about 480 °C.

Alloy 400 shows good resistance to sulfuric and hydrofluoric acids. Aeration however will result in increased corrosion rates. This alloy may be used to handle hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosive attack.

Resistance to neutral alkaline and acid salts is shown in Alloy 400, but the alloy displays poor resistance with oxidizing acid salts ,such as ferric chloride.

Alloy 400 has excellent resistance to chloride ion stress corrosion cracking.
