Home > Electrodes > AWS Class E347T0-1/T0-4 Flux Core Wire
The E347T0‑1/T0‑4 flux-cored welding wire is produced in accordance with the American Welding Society (AWS) A5.22 specification. It’s specifically tailored for gas-shielded flux-cored arc welding (FCAW-G) of stabilized austenitic stainless steels, including grades like 304, 304L, 321, and 347. The stabilizers, which can be niobium/columbium or titanium, help reduce carbide precipitation, providing excellent resistance to intergranular corrosion and performance at high temperatures.
