Monel 400, also known as Alloy 400, with the UNS designation N04400 and W.Nr. 2.4360, is a nickel-copper alloy known for its excellent corrosion resistance, particularly in marine environments. Comprised of approximately 67% nickel and 23% copper, Monel 400 also exhibits good mechanical properties over a wide range of temperatures. This alloy is commonly used in applications such as marine engineering, chemical processing, and equipment for the oil and gas industry due to its resistance to corrosive environments and high strength. Additionally, Monel 400 is known for its ability to withstand high-velocity seawater and is often used in seawater valves, pump shafts, and marine fixtures.
