E309-16
E309/309L gives a weld deposit similar to 309, with reduced carbon levels (0.04% maximum) that offer increased resistance to intergranular corrosion. Type 309/309L is ideal for joining stainless steel to themselves or to carbon or low alloy steels. Alloy 309L is preferred to Alloy 309 for cladding over carbon or low alloy steels, as well as for dissimilar joints which undergo heat treatment.
