Monel R-405 is fabricated, pickled and heat-treated by the same procedures as for alloy 400. It is not recommended for forging. However, R-405 alloy was especially developed for good machinability and is recommended for use with automatic screw machines. The nickel –copper sulfides resulting from the sulfur in its composition act as chip breakers.
This nickel alloy also has the same procedures and processes as alloy 400 and can be joined by standard welding, brazing and soldering techniques. Just as with alloy 400, R-405 can easily be welded by gas – tungsten arc, gas metal arc, or shielded metal arc processes using appropriate filler metals. There is no need for post weld heat treatment, however, thorough cleaning after welding is critical for optimum corrosion resistance, otherwise there is the risk of contamination and embrittlement.
