ER309L Spools

ER309L: used to weld base metals of similar composition in wrought or cast form; also to weld dissimilar alloys like mild steel and the stainless steels, as well as for direct overlay on mild steel for corrosion applications; may weld type 304 and similar base metals where severe conditions may exist. The lower carbon content in wire will help avoid possibility of intergranular carbide precipitation. ER309L stainless steel exhibits high strength and good toughness over a wide range of temperatures. Shielding gas required, usually 100% Argon.

Conforms to AWS A5.9 ASME SFA A5.9. Available wire diameters: 0.023", 0.030", 0.035" and 0.045".
