DETAILS
BLUE MAX® MIG 2594 is a super duplex grade electrode that provides matching chemistry and mechanical property characteristics to super duplex wrought and castings. The electrode is over-alloyed 2-3% in nickel to provide the optimum ferrite/austenite ratio in the finished weld resulting in high tensile and yield strength and superior resistance to stress corrosion, cracking (SCC) and pitting corrosion
Features
- A super-duplex grade electrode that provides matching chemistry and mechanical property characteristics to wrought superduplex alloys such as 2507 and Zeron100, as well as to super-duplex casting alloys (ATSM A890)
- The electrode is over-alloyed 2-3% in nickel to provide the optimum ferrite/austenite ratio in the finished weld resulting in high tensile and yield strength and superior resistance to stress corrosion, cracking (SCC) and pitting corrosion
- Q2 Lot® - Certificate showing actual wire composition and calculated ferrite number (FN) available online
