ER309L
AWS A5.9 ER309L
Description：
A super low carbon stainless steel welding wire has high deposition efficiency, used for joining similar 309L alloys or for joining 300-series stainless steels to carbon or low alloy steels. The low carbon content to help prevent intergranular corrosion. Used to weld super low carbon 24%Cr13%Ni and similar stainless steels, like ASTM 309S etc.
