Alloy ER 2594 is a superduplex welding wire.  The Pitting Resistance Equivalent Number (PREN) is at least 40, thereby allowing the weld metal to be called a superduplex stainless steel.  This welding wire provides matching chemistry and mechanical property characteristics to wrought superduplex alloys such as 2507 and Zeron 100 as well as superduplex casting alloys (ASTM A890). This welding wire is overalloyed 2-3 percent in Nickel to provide optimum ferrite/austenite ratio in the finished weld.  This structure results in high tensile and yield strength along with superior resistance to SCC and pitting corrosion.


Set the parameters to obtain a heat input of 10,000 -30,000 Joules/inch.  Pre-heat is not required.  The interpass temperature should be maintained at 300ºF max.  If post weld annealing is required this weld metal will require a higher annealing temperature than that required by the duplex base metal.



Alloy ER 2594 is a stainless steel TIG, MIG and SUB-ARC wire used for welding.
