AK-ER309LSi
Standard:
EN ISO 14343-A:G 23 12 LSi
AWS A5.9 ER309LSi
GB/T 29713 S309LSi
Description: A super low carbon and high silicon stainless steel welding wire have high deposition efficiency, and is
used for joining similar 309L alloys or for joining 300 series stainless steels to carbon or low alloy steels. The low
carbon content helps prevent intergranular corrosion and higher silicon increase weld puddle fluidity, suitable for high-
speed welding.
Application: Used to weld super low carbon 24%Cr13%Ni and similar stainless steels, like ASTM 309S etc.
