MIG Welding Wire for Stainless Steel

Join stainless steel with this welding wire.

ER308L

Image of Product. Front orientation. MIG Welding Wire.

ER308L wire is for 304 and 304L stainless steel. It creates welds that hold even in cryogenic temperatures.

ER308LSi

ER308LSi wire is for 304 stainless steel. It has a higher silicon content than ER308L wire, so it flows more easily when melted and fills in more of the space between the two pieces of your weld. It’s also better where appearance matters because it creates smoother welds.
