What is AWS Class ER347 SAW & Flux?
AWS Class ER347 SAW wire is an austenitic stainless steel consumable that’s stabilized with niobium (columbium) to avoid carbide precipitation. Its typical composition features around 18–21% chromium, 9–11% nickel, and a controlled amount of niobium. When paired with the right SAW flux, the weld metal produced shows impressive tensile strength, excellent ductility, and dependable impact toughness. It also offers strong resistance to intergranular corrosion and maintains stable mechanical properties even at elevated temperatures.
