AWS Class E347T0-1/T0-4 flux-cored wires are specifically designed for welding stainless steels with excellent corrosion resistance. Chemically, they typically contain 18–20% chromium, 8–10% nickel, with controlled additions of niobium and manganese to enhance stability and reduce carbide precipitation. Mechanically, these electrodes provide high tensile strength (around 550–600 MPa) and good elongation (35–40%), ensuring durable, crack-resistant welds. They offer excellent arc stability, smooth bead appearance, and minimal spatter. Ideal for critical applications, E347T0-1/T0-4 wires are widely used in chemical, petrochemical, and food-processing industries where corrosion resistance and weld integrity are essential.

The AWS Class E347T0-1/T0-4 Flux Core Wire is an austenitic stainless steel filler metal that’s alloyed with chromium, nickel, and columbium (niobium) to boost corrosion resistance and prevent sensitization. Thanks to its low-carbon makeup, it reduces the risk of intergranular corrosion, while the flux-cored design guarantees stable arc performance, smooth bead formation, and easy slag removal. The weld metal produced is known for its impressive tensile strength, ductility, and toughness across a wide temperature range, resulting in strong, crack-resistant welds that are perfect for critical applications.
This flux core wire is a popular choice for welding AISI 347 stainless steels and similar alloys in various industries, including chemical, petrochemical, marine, and food processing. Common applications include piping systems, pressure vessels, heat exchangers, storage tanks, and structural components that face corrosive environments and thermal cycling. It’s especially effective for repair, maintenance, and fabrication welding, as well as for joining different types of stainless steels, where resistance to pitting, crevice corrosion, and thermal stress is crucial, all while maintaining high productivity in both shop and field operations.
