Product Description

Monel Alloy 400

Monel Alloy 400 (NA13, N04400) is a nickel-copper alloy resistant to seawater and steam at high temperatures and widely used in the chemical, oil and marine industries. As a solution strengthened material, Monel Alloy 400 displays good strength, toughness and corrosion resistance at temperatures up to 400°C.

Monel Alloy 400 (NA13, 2.4360) is supplied by Columbia Metals in the cold worked condition as standard.

Monel Alloy 400 (NA13, 2.4360) is used for offshore and marine applications and for chemical processing.

Its corrosion resistance is particular strong in rapid flowing brackish water or seawater. Monel Alloy 400 exhibits good resistance to hydrofluoric and dilute non-oxidising acids, alkalis and salts. It resists corrosion by dry chlorine and hydrogen chloride and is not susceptible to stress corrosion cracking. Monel Alloy 400 (NA13) is readily cold formable and weldable.

Mechanical Properties of Monel Alloy 400

Ultimate Tensile Strength (N/mm²) Proof Stress (N/mm²) Elongation (%) Hardness (HB)
480-600 170-415 20-35 35 HRC max


Alloy 400 is a solid-solution binary. As nickel and copper are mutually soluble in all proportions. It is a single-phase

alloy. It has a face-centered cubic lattice structure with a lattice parameter of 3. A


Alloy 400, with an excellent combination property, is a corrosion resistent alloy in a wide range of use and applications.

It has an excellent corrosion resistance in the media of hydrofluoric acid and fluorine and also a good corrosion resistance to hot strong alkali liquor. Besides it also resistant to corrosion in the neutral solution, water, sea water, air,organic compound etc. One important character of the alloy is that the s tress corrosion cracking normally doesn’t occur and it has a good machinability

Corrosion Resistance

Alloy 400 exhibits resistance to corrosion by many reducing media. It is also generally to attack by oxidizing media than

higher copper alloys. This versatility makes alloy 400 suitable for service in a variety of environment;

Alloy 400 is widely used in marine applications. While alloy 400 products exhibit very low corrosion rates in flowing seawater

Stagnant conditions have been shown to induce crevice and pitting corrosion. Alloy 400 is also resistant to stress corrosion cracking and pitting in most fresh and industrial water

Alloy 400 offers exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point;

It is perhaps the most resistant of all commonly used engineering alloys Alloy 400 is also resistant to many forms of sulfuric and hydrochlorid acids under reducing


Monel 400 is a material in a variety of applications, and is applied in many industrial areas. tubing

  • Feed-water and steam Generator in power plants
  • Brine heaters and evaporator bodies in seawater desalination plants
  • Pumps and values used in the manufacture of chlorinated hydrocarbons
