What is Monel 400 Fasteners?
Monel 400 fasteners, also referred to as its UNS number N04400, is a nickel-copper alloy that is majorly composed of nickel 67% and copper 23% . It has great saltwater resistance, hydrofluoric acid resistance, alkali and stress corrosion cracking. Monel 400 is not hardened by heat, however, it can be hardened by cold working because it has a solid solution alloy structure.
This speciality chemical structure and metallurgical balance is what makes the Monel 400 fasteners the most suitable in those cases where the overall requirements are both mechanical strength and corrosion protection.
