What is AWS Class ER347 MIG and TIG Filler Welding Wire?

ER347 is a columbium (niobium)-stabilized austenitic stainless steel welding wire that contains about 19–21% chromium, 9–11% nickel, along with small amounts of columbium and tantalum. This stabilization is key in preventing carbide precipitation, which enhances its resistance to intergranular corrosion during and after the welding process. The wire typically boasts tensile strengths between 75–85 ksi and retains excellent weldability and toughness, even in challenging high-temperature or corrosive settings. ER347 is effective in both MIG and TIG welding, ensuring clean, defect-free welds on stainless steel base materials.
