E2594-16
Alloy 2594 is a superduplex grade electrode that provides matching chemistry and mechanical property characteristics to wrought superduplex alloys such as 2507 and Zeron 100, as well as to superduplex casting alloys (ASTM A890). The electrode is overalloyed 2% to 3% in nickel to provide the optimum ferrite/austenite ratio in the finished weld. This structure results in high tensile and yield strengths and superior resistance to SCC and pitting corrosion.
