What is Nickel Alloy 400 / Monel 400 ?

It is a single-phase, solid-solution nickel-copper alloy, typically composed of approximately 67% nickel and 30% copper. This unique composition delivers outstanding performance in a wide range of corrosive media, including seawater, hydrofluoric acid, sulfuric acid, and alkaline solutions. Unlike many iron-based alloys, it is not susceptible to chloride-induced stress corrosion cracking, a common failure mode in marine and chemical processing environments. 

One of the defining characteristics of Monel 400 is its excellent mechanical properties, which are maintained from sub-zero temperatures up to approximately 550°C (1020°F). The alloy is also non-magnetic under most conditions, a crucial feature for applications involving sensitive electronic equipment or specialized instrumentation. Its combination of strength, toughness, and exceptional corrosion resistance makes it a highly reliable material for pumps, valves, shafts, and piping systems used in corrosive marine and chemical environments. Furthermore, its good weldability and workability allow for straightforward fabrication into complex components, providing engineers with design flexibility without compromising performance.
