Monel 400 is a high-strength nickel-copper solid solution alloy with excellent corrosion resistance in alkaline, saltwater and mild acid environments. It features stable mechanical properties from low to moderate temperatures, good ductility and excellent weldability. The alloy performs exceptionally well in marine atmosphere, seawater, brine and chemical processing media, and is widely used in marine engineering, valve fittings, pump parts, heat exchangers and marine pipeline systems.

Advantage

1.Excellent seawater and marine atmospheric corrosion resistance 2.High mechanical strength and good toughness at normal and low temperatures 3.Fine resistance to alkali, salt solution and non-oxidizing acid corrosion 4.Superior processability, weldability and long service life in harsh working conditions
