Monel® R-405 is a nickel-copper alloy created and manufactured by Special Metals, also known as UNS N04405, it is part of the Monel family of superalloys. Typically found in rod, bar, and wire form, Monel 405 offers enhanced machinability due to a higher sulfur content. In addition, this superalloy also has excellent corrosion resistance and high strength properties. These characteristics make it ideally suited for difficult marine and chemical environments. It is also resistant to sulfuric acids, and performs well in subzero temperatures. Monel R-405 has a chemical composition of:

  • Nickel 63%
  • Copper 28-34%
  • Carbon .3% max
  • Manganese 2% max
  • Iron 2.5% max
  • Silicon 0.5 max
  • Sulfur 0.025-0.060%

Monel R-405®is very similar to Monel 400®except for its greater sulfur content. Monel R-405® also has the same corrosion resistance and physical properties as the Monel R405® with a slightly different range of mechanical properties. Monel R-405® was developed for good machinability.


  • It is approved by ASME for use in boilers, pressure vessels, and nuclear vessels
  • Can be fabricated, pickled, and heat-treated exactly like Monel 400


  • 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.

Fabrication and Heat Treatment

The machinability of MONEL R405 is difficult as it work-hardens during machining. The conventional machining techniques used on iron alloys may be used for this alloy. Welding methods including gas-arc welding, metal-arc welding, gas-metal-arc welding and submerged-arc welding are recommended on this alloy. Cold working may be done using soft die materials for better finishing.
