Does Monel 400 rust?
Monel 400 is a nickel-copper alloy (approximately 67% Ni - 23% Cu) resistant to high temperatures in seawater and steam as well as salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy has good corrosion resistance, good weldability and high strength. It has low corrosion rates in fast-flowing saltwater or seawater, excellent resistance to stress corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions makes it widely used in marine applications and other non- Oxidizing chloride solution.
Monel 400
This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids after degassing. As expected from its high copper content, Alloy 400 is rapidly attacked by nitric acid and ammonia systems.
Monel 400 has excellent mechanical properties in sub-zero temperatures and can be used at temperatures up to 1000° F. It has a melting point of 2370-2460° F. However, Alloy 400 has lower strength in the annealed condition, so there are various tempering states that can be used to increase strength.
