Stainless Tig Rod - ER316L
ER316L stainless TIG rod is a molybdenum-bearing GTAW filler (AWS A5.9) for welding 316 and 316L stainless. The molybdenum gives superior pitting and chloride-corrosion resistance — the standard for marine, chemical, pharmaceutical, and food-grade equipment. Low-carbon; 36" cut lengths in 1/16", 3/32", and 1/8", under 100% argon, DCEN.

Frequently Asked Questions
When do I need ER316L instead of ER308L?
For 316/316L base metal and any service involving chlorides, salt water, or corrosive chemicals — the molybdenum resists the pitting that would attack a 308L weld.
Is ER316L used for marine work?
Yes — it's a standard filler for marine, chemical, and food/pharmaceutical stainless equipment.
