About ER 308L Tig Wire

ER 308L TIG wire is a stainless steel filler material used in TIG welding. It’s designed for welding 304 and 304L grade stainless steels. The “L” signifies low carbon content, reducing carbide precipitation and increasing resistance to intergranular corrosion. This wire provides strong, ductile welds with excellent corrosion resistance.
