Washington Alloy, TM309L-SI 05, Welding Filler Rod, 3/32 in, 36 in, ER309L-Si Stainless Steel, 87,200 psi tensile strength

ER309LSi has a higher level of silicon than ER309L combined with a carbon content lower than ER309. The increased silicon level provides better arc stability and a smoother bead appearance while an average 02% carbon level reduces carbide precipitation. Typical applications would include those of ER309 and ER309L.
