ER308L is a low-carbon austenitic stainless steel welding wire designed for welding 304 and 304L stainless steels.
The reduced carbon content minimizes the risk of intergranular corrosion after welding, making ER308L suitable for applications requiring good corrosion resistance and reliable weld integrity.
It is widely used in food processing equipment, chemical tanks, structural fabrication, and general stainless steel construction.
