What are Monel 400 Pipes?

The Monel family of alloys was developed by David H. Browne, the head metallurgist at International Nickel Co. It was patented in 1906 and given the name Ambrose Monel, the then-president of the United States. Monel alloy 400 (UNS N04400. W.Nr. 2.4360, 2.4361) is a member of this family. An alloy of nickel and copper with a nickel content of about 67 percent, it is renowned for its resistance to corrosion caused by acids, seawater, and other corrosive conditions. Corrosion resistance makes Monel 400 Pipes ideal for maritime applications such as piping systems, pump shafts, seawater valves, etc. Additionally, heat exchangers, towers for distilling crude oil, boiler feeds, and equipment for chemical plants also typically contain it. This nickel-copper alloy, which contains around 67 percent nickel, is renowned for withstanding corrosion from acids, seawater, and other hostile conditions.

Only cold-worked to hardness, Monel 400 pipe has great strength, excellent weldability, and corrosion resistance. Monel 400 pipe has excellent mechanical qualities at subzero temperatures and may be used in temperatures up to 1000° F, despite having a low strength in the annealed condition when utilising a variety of tempers.

Due to its resistance to corrosion, Monel 400 pipe is ideal for use in marine applications such as piping systems, pump shafts, seawater valves, etc. It is also frequently found in heat exchangers, boiler feeds, towers for distilling crude oil, and equipment for chemical plants.

Applications of Monel 400 Pipes

In a variety of fluids, including seawater, hydrofluoric acid, sulfuric acid, and alkalies, the material exhibits high strength and outstanding corrosion resistance.

an alloy made of solid solutions that can only be hardened through cold working

Exceptional resistance to numerous corrosive environments and high strength and toughness over a wide temperature range.
