Description: This classification is the same as AFM ER308L, except for the higher silicon
content. This improves the usability of the filler metal in the gas metal arc
welding process. If the dilution by the base metal produces a low ferrite or
fully austenitic weld, the crack sensitivity of the weld is somewhat higher than
that of a lower silicon content weld metal.
