Monel 400 Nickel Alloy

The Monel 400 nickel alloy, a solid solution alloy manufactured by XINHUA, can be hardened only by cold processing. It shows pretty high strength and toughness over a wide range of temperatures and good resistance to numerous corrosive environments.

In addition, Monel alloy 400 has excellent resistance to chloride-ion stress corrosion cracking, to neutral, alkaline and acid salts (especially the salts containing oxidizing acids), and to sulfuric acid and hydrofluoric acid. This nickel-copper alloy has been widely used in many fields, including marine engineering, chemical and hydrocarbon processing equipment, as well as oil industry.
