Harris Products Group, 309LTF0, TIG Welding Alloy, 309L, Stainless Steel, 58,000 psi Yield Strength, 87,000 psi Tensile Strength, 0.03% Carbon Content

309L stainless steel TIG (GTAW) welding alloy has similar usage as 309, but the 0.03% maximum carbon content, 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.
