Covered Arc Welding Electrode
E309/309L-16 is a stainless steel electrode idea; for joining stainless steels to themselves or to carbon and lo-alloy steels. Carbon content in the weld metal is held to .04% max which gives it increased resistance to intergranular corrosion.
Typical Applications : joining hard to weld steels and for dissimilar metal welding wherever maximum ductility is required when joining dissimilar steels to themselves or to stainless steels
