AWS A5.9 ER2594
ASME SFA 5.9 ER2594
ER2594 is a super duplex stainless steel used for welding matching
or similar alloys such as ASTM A890, UNS S31260(DP-3), S32750 (2507), S32760 J93380 (Zeron 100), S32550 (Ferralium 255). Also
found for welding UNS S32550, J93370, and J03372 when used without sulfurous andsulfuric service
conditions. It may also be used to weld carbon and low alloy steels to duplex as well as root runs on UNS S32205 & J92250. Interpass
temperature 300° F max and heat input of 10-30 kJ/in.; Heat Input = Voltage x Amperage x 6 ٪Travel Speed (inch/Minute) x 100.
Weld metal should have very good resistance to stress corrosion cracking and pitting with an austenite & 45-55 % ferrite matrix.
