309L stainless steel GTAW (TIG) welding alloy has similar usage as 309, but the 0.03% maximum carbon content (0.03% maximum), reduces the possibility of carbide precipitation that can cause weld corrosion, to increase resistance to intergranular corrosion. Used for welding similar alloys in wrought or cast form. Occasionally used for welding 18-8 base metals when severe corrosion conditions exist, and, at times, welding dissimilar steels. Conforms to AWS A5.9. Packaged for portable welding machines. Conveniently packaged for point-of-purchase display.
