DESCRIPTION

Monel® 400 is a Nickel-Copper alloy with high strength and toughness and remains ductile even at subzero temperatures. Age-hardening treatments are not required to obtain the high strength properties of Monel® 400 because it is a solid-solution alloy that is hardened only through cold working. The alloy is resistant to corrosion in many reducing environments, offering excellent corrosion resistance in seawater, hydrofluoric acid, sulfuric acid, and hydrochloric acid. Monel® 400 also shows resistance to stress corrosion cracking and pitting in fresh water, is resistant to oxidization and can operate from cryogenic temperatures to 500°F (260°C).
