ER 316 ER 316L ER 316LSi Welding Wire Diameter 0.8 - 3.0mm AWS A 5.9
Standard: AWS A 5.9
ER 316: Welding wire usually used for welding wrought and cast forms of similar alloys. ER312 contains about 2% molybdenum to increase its creep resistance at elevated temperature. The lower ferrite level of this alloy reduces the rate of corrosion and is suitable for high temperature service applications.
ER 316L: Welding wire similar to ER316, with controlled carbon content (0.03% maximum) to reduce the possibility of formation of inter-granular carbide precipitation. Used principally for welding molybdenum-bearing low carbon austenitic alloys. ER316L is not as strong as ER316H at elevated temperature.
ER 316LSi: Welding wire similar to ER316L: but the higher silicon content (0.65-1.00%) improves wash and wetting behavior in the gas shielded welding processes. Weld bead are exceptionally smooth with this alloy. Higher productivity could be realized in MIG welding.
