Super Alloy Monel 400 UNS N04400 Nickel Alloy
Monel 400 material is a nickel-copper alloy (approx. 67% nickel - 23% copper) resistant to seawater and steam at high temperatures, as well as salt and corrosive solutions.
Description
This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids after degassing. As expected with its high copper content, the 400 alloy is rapidly attacked by nitric acid and ammonia systems.
Products Description
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-oxidising chloride solutions. This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids after degassing. Due to the high copper content,
