ER309L Rods

ER309L is to weld dissimilar alloys like mild steel and the stainless steels, and also for direct overlay on mild steel for corrosion applications; at times used for welding "18-8" base metals when severe corrosion conditions exist or dissimilar metals; Low carbon content of max. 0.03% will reduce the 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 rod diameters: 0.045", 1/16”, 3/32” and 1/8”; length 36”. Single end stamped.
