What is AWS Class ER309/309L SAW & Flux?
AWS Class ER309/309L SAW wire is an austenitic stainless steel consumable that contains about 22–24% chromium and 12–14% nickel. The low-carbon 309L version helps reduce the risk of intergranular corrosion. When paired with the right SAW flux, the weld metal produced boasts good tensile strength, excellent ductility, and reliable impact toughness. These consumables maintain stable arc characteristics, resist hot cracking, and deliver consistent mechanical properties, even in high dilution scenarios.
