ER316L Stainless Steel Welding Wire Supplier | MIG & TIG Filler Metal for 316/316L Stainless Steel
ER316L is a low-carbon stainless steel welding wire developed for joining 316 and 316L stainless steels in corrosive service environments. Its 2–3% molybdenum content provides higher resistance to pitting and crevice corrosion than ER308L, making it a preferred choice for chloride-containing applications.
ER316L is widely used for chemical processing equipment, marine components, pharmaceutical systems, and food processing machinery. The low carbon composition helps maintain corrosion resistance after welding by reducing the risk of intergranular corrosion.

The mechanical properties of ER316L ensure reliable weld performance, maintaining strength and ductility even in high-temperature environments.
Ø Low Carbon Austenitic Structure: The low carbon content reduces carbide precipitation, ensuring resistance to intergranular corrosion in welded areas.
Ø Molybdenum Addition for Enhanced Corrosion Resistance: The 2-3% molybdenum content significantly improves resistance to pitting and crevice corrosion in chloride-rich environments.
Ø Excellent Weldability: ER316L has smooth arc performance, ensuring minimal spatter and consistent welds, even in difficult positions.
Ø Superior Resistance to High-Temperature Corrosion: Suitable for applications requiring high temperature stability and corrosion resistance.
Ø Versatile for Dissimilar Welding: Works well for welding 316L to 304L and other stainless steels, offering flexibility in a wide range of welding applications.
