Monel 400

Overview of Monel 400

Monel 400(UNS N04400) is an alloy mainly composed of nickel and copper, which is widely used in chemical, Marine engineering and electric power fields due to its excellent corrosion resistance and mechanical strength. Monel 400 is also known as Alloy 400, Monel 400 has high strength, excellent corrosion resistance, good ductility and thermal conductivity. Typical applications of the Monel 400 include heat exchangers, valves, Marine engineering, chemistry and hydrocarbon processing.

This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated lye. At the same time, it is also resistant to corrosion of neutral solution, water, seawater, atmosphere, organic compounds, etc.An important feature of the alloy is that it generally does not produce stress corrosion cracks and has good cutting performance. The structure of Monel400 alloy is a high strength single phase solid solution. The UNS number of this alloy is N04400. Standard: ASTM B127, B163, B164, B165, B564, B725, B730, B366, SMA 4675, 4730, SMA 4544, 4731
