Top AWS Class E309LT1-1/T1-4 Flux Core Wire Manufacturing Company in Naypyidaw

The E309LT1-1/T1-4 flux-cored welding wire falls under the American Welding Society (AWS) standard A5.22 (also known as ASME SFA-5.22). It’s designed for gas-shielded flux-cored arc welding (FCAW-G) of austenitic stainless steels, especially those with around 22% chromium and 12% nickel. It’s also great for joining stainless steels to carbon or low-alloy steels. This wire comes in both “T1-1” (shielded gas) and “T1-4” versions, making it suitable for all-position welding with either a mix of argon and CO2 or 100% CO2 shielding.
