Nickel Alloy Properties
Monel 400 (UNS N04400) offers excellent corrosion resistance in a variety of environments. Corrosion rates are low, particularly in rapidly flowing brackish or seawater. The product also provides excellent resistance to stress-corrosion cracking in freshwater. Monel 400 is a solid-solution alloy which can be hardened by cold working. The product promotes attractive performance characteristics, including good weldability and high strength and retains its properties at sub zero temperatures. The material is also suitable for use in high-temperature environments up to 538° C. Due to the alloys copper content, Monel 400 is a viable, low cost alternative when compared to commercially pure nickel.
