Monel 400 material 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.

Monel400 is an amount of the largest and most versatile, excellent overall performance of corrosion resistant alloys.

This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, hot concentrated alkali is also excellent in corrosion resistance. Also resistant to neutral solution, water, sea water, air, organic compounds corrosion.

An important feature of the alloy is generally not produce stress corrosion cracking, good cutting performance.

Its chemical composition is mainly composed of 30% Cu and 65% Ni plus a small amount of Fe (1% -2%) of the composition. Due to differences in the chemical composition on it can have a variety of alloy grades, but the corrosion resistance and no significant difference between them. Monel400 alloys more resistant to corrosion than reducing media pure nickel, and copper is more resistant to oxidation than the media corrosion.



Monel400 is a versatile material, can be applied in many industrial areas:

1. The power plant seamless pipes, steam pipes

2. The water exchange and evaporator

3. sulfuric acid and hydrochloric acid environment

4. Crude Distillation

5. In the sea water pump shaft and propeller equipment used

6. The nuclear industry for the manufacture of uranium isotope separation and refining equipment

7. hydrochloric equipment manufacturing pumps and valves
