OVERVIEW:

MONEL R405 is a Nickel-Copper alloy, resistant to sea water and steam at high temperatures as well as to salt and caustic
solutions. 
MONEL R405 is a nickel-copper alloy with excellent corrosion resistance in a wide variety of media. MONEL R405 is
characterized by good general corrosion resistance and moderate to high strength. MONEL R405 has been used in a variety of
applications. It has excellent resistance to rapidly flowing brackish water or seawater. It is particularly resistant to hydrochloric
and hydrofluoric acids when they are de-aerated. MONEL R405 is slightly magnetic at room temperature. MONEL R405 is
widely used in the chemical, oil and marine industries.

• Corrosion resistance in an extensive range of marine and chemical environments. From pure water to nonoxidizing
• mineral acids, salts and alkalis.
• MONEL R405 is more resistant to nickel under reducing conditions and more resistant than copper under oxidizing
• conditions, it does show however better resistance to reducing media than oxidizing.
• Good mechanical properties from subzero temperatures up to about 480C.
• Good resistance to sulfuric and hydrofluoric acids. Aeration however will result in increased corrosion rates. May be
• used to handle hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosive attack.
• Resistance to neutral, alkaline and acid salts is shown, but poor resistance is found with oxidizing acid salts such as
• ferric chloride.
• Excellent resistance to chloride ion stress corrosion cracking.

*Due to sulfur addition for free machining, welding is not possible for MONEL R405.

Applications:

• Feed water and steam generator tubing.
• Brine heaters, sea water scrubbers in tanker inert gas systems.
• Sulfuric acid and hydrofluoric acid alkylation plants.
• Pickling bat heating coils.
• Heat exchangers in a variety of industries.
• Transfer piping from oil refinery crude columns.
• Plant for the refining of uranium and isotope separation in the production of nuclear fuel.
• Pumps and valves used in the manufacture of perchlorethylene, chlorinated plastics.
• Monoethanolamine (MEA) reboiling tube.
• Cladding for the upper areas of oil refinery crude columns.
• Propeller and pump shafts.
