Alloy ER 308LSi is used to weld base metal of similar composition such as AISI 310, 302, 304, 304L, 305, 308, 308L and 347. This classification is the same as ER308L, except for the higher silicon. 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.
