ER309L Spools Stainless Steel Welding Wire Blue Demon

ER309/309L is very similar to type 309
except for the carbon content being lower
than .03%. The extra low carbon content
provides good resistance to carbide
precipitation and intergranular corrosion.
ER309L works well for dissimilar joints that
undergo heat treatment.
