Monel 400 is a single-phase, nickel-copper alloy that offers superior resistance to many corrosive environments over temperatures ranging from sub-zero to 800°F. This alloy is only hardenable through cold working, rather than heat treatment. Caution is advised in applications where strong nonmagnetic characteristics are desired. The ratio of copper to nickel in alloy 400 is almost identical to that found in the ore the metal is derived from. This alloy is one of the most commonly used corrosion-resistant alloys commercially produced.

Monel 400 has been widely used in a variety of industries and has been particularly useful in the marine industry and chemical processing industry. Typical applications include pumps and valves, propeller shafts, marine fixtures and fasteners, electronic components, springs, chemical processing equipment, fresh and saltwater tanks, process vessels and piping, boiler feedwater heaters and other heat exchangers.

Monel 400 exhibits resistance to corrosion by many reducing media. It is one of the few alloys that can be used in contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. Exceptional resistance has been proven in hydrofluoric acid in all concentrations up to the boiling point. Monel 400 is also resistant to many forms of sulfuric and hydrochloric acids under reducing conditions. Corrosion resistance behavior in seawater is excellent. Monel 400 offers about the same corrosion resistance as nickel but with higher maximum working pressures and temperatures and at a lower cost due to its superior ability to be machined.

Like most other nickel alloys, Monel 400 is typically tough to machine and will work harden. However, excellent results can be obtained if you make the correct choices for tooling and machining.
