DETAILS
LINCOLN® ER2594 electrode is over-alloyed with nitrogen 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 super duplex alloys such as 2507 and Zeron 100, as well as to super-duplex casting alloys (ATSM A890)
- The electrode is over-alloyed with nitrogen 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
- Ink jet printing identification on entire length of electrode
- Q2 Lot® - Certificate showing actual wire composition and calculated ferrite number (FN) available online
Typical Applications
- Process Pipework
- Pumps and Valves
- Pressure Vessels
- Used to weld super duplex stainless steels such as Type 2507 and Zeron 100
