ASTM B163 Monel 400 UNS N04400 Seamless Bright Surface Nickel Copper Alloy Tube
蒙乃尔 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.
This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids after degassing. Due to its high copper content， MONEL 400 is quickly attacked by nitric acid and ammonia systems. MONEL 400 has good mechanical properties below freezing， with service temperatures up to 1000 degrees Fahrenheit and a melting point of 2370-2460 degrees Fahrenheit. However， alloy 400 has low strength in the annealed condition， so a variety of temperatures can be used to increase strength.
