Description: AFM ER347Si is the same as AFM ER347, 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.
