AWS A5.9 ER308LSi
ASME SFA 5.9 ER308LSi
ER308LSi has a higher silicon content along with a low carbon content. The increased silicon level provides better arc stability and a smoother
bead appearance while an average .02% carbon level reduces carbide precipitation. ER308LSi produces excellent quality fillet and butt welds.
Typical applications would include those of ER308 and ER308L welding wires.
