Stainless Solid wire - ER308L
ER308L stainless steel solid wire is the standard filler for welding 304 and 304L austenitic stainless (AWS A5.9). Its low carbon content resists intergranular corrosion (carbide precipitation), giving clean, corrosion-resistant welds — the everyday choice for stainless fabrication, food and dairy, and sanitary work. Spools in .030", .035", and .045".

Frequently Asked Questions
What is ER308L used for?
Welding 304 and 304L stainless steel — the most common austenitic grade — in fabrication, food/dairy, and sanitary applications.
ER308 vs ER308L?
The “L” is low-carbon, which resists carbide precipitation and intergranular corrosion. Use ER308L for L-grade base metals and any corrosion-critical service.
