MONEL 400 (UNS NO. N04400) is a nickel-copper alloy that has excellent corrosion resistance, especially in reducing conditions. This metal also exhibits excellent ductility and thermal conductivity, making it suitable for a wide variety of applications. It is also known by other names, including Phyweld 400 and Nicorros LC. This article will provide an overview of Monel 400's characteristics and use in various industries. Also, learn about its physical properties and chemical composition.


MONEL 400 (UNS NO. N04400)sheets can be purchased in wide widths (200mm to 6000mm) and various thicknesses, ranging from 0.3mm to 20mm. The material has a high density, compared to 304 grade sheets of steel. 


Navstar Steel produces both Monel 400 Coil and Strip for a wide range of high temperature applications. Monel 400 Sheet is available in both hot and cold rolled finishes. This material has a high melting point (1350° Celsius) and is hard enough to support cutting operations.


INCONEL 800 (UNS NO. N08800) has excellent corrosion resistance in seawater and steam. It resists corrosion in freshwater and is rustproof in saltwater. It is not corroded by nitric acid but does tend to be a difficult metal to machine. Because of its high resistance to oxidizing and reducing environments, it is often used in equipment for chemical processing, valves, and hydrocarbon processing. However, it has low strength in annealed and tempered conditions.


Monel 400 is an excellent choice for a variety of welding applications. Welding is possible in a gas-tungsten arc, shielded metal arc, and friction weld processes. This metal does not require post-weld heat treatment. However, thorough cleaning after welding is essential for optimum corrosion resistance. Improper cleaning may cause embrittlement and contamination. MONEL 400 (UNS NO. N04400) has variable mechanical properties, and while it is difficult to machine, it is worth the effort.


Another notable property of Monel 400 is its ability to resist corrosion in a variety of environments. It is resistant to acids, and it's moderate to high tensile strength makes it a valuable metal for a wide range of applications. Because of this, it is frequently used in the chemical industry, nuclear power, and marine industries. Aside from its high strength, Monel 400 also resists wear and oxidation, making it a versatile alloy.


Monel 400 pipe fittings are typically used in hydrocarbon processing and marine engineering. Monel pipes are available in various cut lengths and can be custom machined for the piping requirements of the user. Monel 400 pipe fittings are made of copper-nickel alloy, which is highly corrosion-resistant and suitable for corrosive environments. Nickel, manganese, and iron are all important elements in this alloy.
