ASTM B163 Monel 400 UNS N04400 Seamless Nickel Copper Alloy Tube Bright Surface

Monel 400 is a nickel-copper alloy (approx. 67% nickel - 23% copper) that is resistant to seawater and high-temperature steam as well as salt and corrosive solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy has good corrosion resistance, weldability and high strength. It has a low corrosion rate in fast-flowing brackish or seawater, excellent resistance to stress corrosion cracking in most freshwaters, and is also resistant to a wide range of corrosive conditions, making it widely used in marine and other non-oxidizing chloride solutions.
