Monel 400 is also known as UNS N04400,NCu30, W.N,2.4360, Alloy400,
Noo4400, NCU30-LC
Monel 400 alloy has excellent corrosion resistance to fluorine gas,
hydrochloric acid, hydrofluoric acid and their compounds. At the
same time, it is more resistant to corrosion in the sea than
copper-based alloys. Monel400 is resistant to corrosion in
hydrochloric acid with a concentration of less than 85%. Monel400
is one of the main raw materials in hydrochloric acid. Monel400
alloy is not only corrosion-resistant, but also less porous
corrosion, intergranular corrosion and so on. The corrosion rate is
lower than 0.025mm/a. Monel400 in the air continuous operation
temperature is generally around 600℃ and the corrosion rate is less
than 0.026mm/a. in high temperature vapor.
Because of the high nickel composition of Monel400 alloy, it can
withstand the corrosion of aqueous ammonia and ammonolysis standard
below 585℃,which can manufacture all kinds of parts with complex
shapes and has been widely used in aerospace, nuclear energy,
petroleum industry and extrusion mold in the above temperature
range.

Monel 400 Strip | UNS N04400
- Metallographic Structure: Most Monel 400 strips are fabricated with
higher strength exclusive-state solid solutions.
- Resistance Ability: Strips made from Monel 400 exceptionally have
superb resistance against different corrosive chemicals, elements
and acids. At the same time, most of these materials are capable of
resisting most water corrosion cases, as well as pitting and stress
corrosion cracking.
- High Temperature Performance: These materials can operate
continuously to its maximum temperature reaching around 600℃.
Application of Monel 400
Monel 400 alloy is a multi-purpose material in many industrial
applications:
1. Seamless water pipe in the power factory
2. Sea-water exchanger and evaporator
3. Sulfuric acid and hydrochloric acid environment
4. Crude distillation
5. Sea-water in the use of equipment and propeller shaft
6. Nuclear industry and used in the manufacture of uranium
enrichment isotope separation equipment
7. Manufacturing hydrochloric acid equipment used in the production
of pump and valve.
