What is AWS Class E309LT0-1/T0-4 Flux Core?

The AWS Class E309LT0-1/T0-4 Flux Core Wire is made up of about 23% chromium and 13% nickel, featuring low carbon content to help reduce intergranular corrosion and prevent carbide precipitation. This wire creates a stable austenitic-ferritic weld deposit that boasts high resistance to cracking. It also offers impressive mechanical properties, including a tensile strength of around 570 MPa and good ductility. Tailored for CO₂ shielding gas, it provides smooth arc characteristics, minimal spatter, and efficient slag removal. This wire is versatile enough for both flat and horizontal welding, excelling at joining stainless steels to carbon or low-alloy steels.
