E309L electrodes are used for welding 22% Cr-12% Ni stainless steel, mild or carbon steel to stainless steel and stainless clad steel. This electrode will produce an austenitic-ferritic, ductile weld deposit that contains a maximum of 0.04% carbon, there-by providing good crack resistance
and inter-granular corrosion resistance superior to that of USA 309 electrodes. Typical applications are similar to those of E309, but where
stronger corrosion resistance is required.
