An Introduction To Monel 400 (UNS N04400)

Monel 400 for Valves, Pumps and Fittings

Monel was first formulated in the 1900s and ever since has proved to be a vital choice of alloy for engineers throughout the world.

This nickel-copper alloy is perfect for valves, pumps, shafts, fittingsand other instrumentation.

This is because it holds excellent resistance when faced with corrosive substances.

It also has an all-round high strength when working in a range of media including sea water and sulfuric acid.

Alloy 400 Proves A Powerhouse In Many Industries

Energy and power are essential to everyday living, and so by default, so is the oil and gas industry.

The UK’s network of gas distribution is used to heat our homes during winter and the work of offshore rigs supplies vital fuels for our everyday transport.

Did you know that the oil and gas industry provides more than 70% of the UK’s total primary energy?

Monel 400 is an alloy used frequently for applications with petrochemical substances, petroleum and gasoline thanks to its powerful properties.

Not only does it provide a benefactor of strength and durability to these industries, but it is also a great choice for aircraft, pulp and paper, and the marine sector.

Forms Available

Tubing (Alloy 400)

Tube Fittings (Elbows, hose couplings, compression fittings, tees and more)

Valves (Used for flow control with high or low pressures)

MONEL® Alloy 400 Properties

Monel 400 is best known for its resistance to corrosive environments. Monel 400 is a nickel-copper alloy that is widely used for its impeccable strength and durability.

The alloys resistance to seawater and brackish water (salt and fresh water mixed together), makes it a fantastic choice for marine and offshore operations.

This alloy is also particularly resistant to hydrofluoric and hydrochloric acids once deaerated.

Other common uses of alloy 400 are:

Valves, pumps, shafts and instrumentation
Chemical processing equipment
Marine engineering applications
Crude oil applications
Flow and seperation
Process vessels and piping
