The "L" in ER308L means low carbon, which eliminates that risk without needing stabilizers like niobium or titanium. Stable Arc, Smooth Puddle, Clean Stringer Beads ER308L maintains consistent arc stability even on thin-gauge stainless. You get predictable puddle behavior, smooth bead profiles, and minimal post-weld cleanup — fewer cold laps, less grinding. Industry Standard for Food-Grade and Sanitary Stainless Work Dairy equipment, restaurant fabrication, food processing machinery, brewing tanks — ER308L is the default rod specified for these applications because of its corrosion resistance and compliance with food-contact weld requirements.
