Note that the designation “Monel®” is registered trademarks of Special Metals Corporation group of companies.


┃ Overview

UNS N04400 is a single phase, solid-solution alloy that can be hardened only by cold working, rather than heat treatment, it has high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments. Monel 400 has excellent mechanical properties at subzero temperatures. Strength and hardness increase with only slight impairment of ductility or impact resistance. The alloy does not undergo a ductile-to-brittle transition even when cooled to the temperature of liquid hydrogen, this is in marked contrast to many ferrous materials.

┃ Application

Chemical Processing: Pumps, valves, heat exchangers, and reactor vessels

Marine Applications: Seawater valves, pump shafts, propeller shafts, fasteners, and other components

Aerospace Industry: Landing gear, fasteners, exhaust systems, and engine components

Oil and Gas Industry: Wellhead components, valves, pump shafts, and tubing

Food Processing: Food handling and processing machinery, heat exchangers, and storage tanks

Electrical and Electronic Components: Electrical connectors, switchgear components, terminals, and in the production of electronic devices

Seawater Desalination: Pumps, valves, heat exchangers, and tubing


┃Corrosion Resistance

Monel 400 exhibits resistance to corrosion by many reducing media and offers exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point. This versatility makes alloy 400 suitable for service in a variety of environments, and is perhaps the most resistant of all commonly used engineering alloys. For example, in most fresh and industrial waters, alloy 400 can resist to stress corrosion cracking and pitting.


┃Machining

Monel 400 can be machined at satisfactory rates with machine tools generally employed by industry. In relieved material is recommended for best machinability and smoothest finish.


┃Welding

Monel 400 is readily joined by conventional processes and procedures. Most of the conventional welding processes may be used to join Monel 400 to itself or dissimilar alloys. The choice of welding product is dependent upon the materials being joined and the environment to which they will be exposed. For some applications, Nickel Welding Electrode 141, INCO-WELD A Welding Electrode, or INCONEL Welding Electrode 112 may be preferred.
