ER-316/316L MIG & TIG Welding Wire

At Metals And Welding Specialities, we supply premium-grade ER-316/316L MIG & TIG Welding Wire designed for outstanding corrosion resistance, durability, and weld integrity in demanding environments. Engineered with precision, this filler metal meets the highest industrial standards and provides exceptional performance when joining austenitic stainless steels of similar composition. The ER-316/316L alloy is a low-carbon variant, offering superior protection against carbide precipitation during welding, which ensures long-term stability and reliability in critical applications.

This welding wire is classified under UNS S31603 and conforms to ASTM A580/A580M standards. Known universally as Type 316/316L Stainless Steel, it is alloyed with controlled amounts of chromium, nickel, and molybdenum, providing excellent resistance to pitting, crevice corrosion, and general oxidation in chloride and marine environments. The low carbon content (the “L” in 316L) minimizes intergranular corrosion, making it ideal for fabrication where post-weld heat treatment is impractical.

Metals And Welding Specialities’ ER-316/316L welding wire delivers a smooth, stable arc with minimal spatter, resulting in clean, high-quality weld beads. It performs consistently in both MIG (GMAW) and TIG (GTAW) processes, whether used for manual or automated welding. Our wire is widely chosen across industries such as petrochemical processing, food and beverage manufacturing, pharmaceuticals, shipbuilding, and offshore structures—anywhere corrosion resistance and hygiene standards are paramount.

When welding stainless steel components exposed to harsh chemicals, saline water, or acidic conditions, the ER-316/316L filler metal offers unmatched protection and mechanical strength. Its metallurgical composition ensures ductility and toughness even at low temperatures, maintaining structural integrity and visual appearance over time. The precision drawing and spooling process at Metals And Welding Specialities guarantees uniform wire diameter, steady feed performance, and consistent metallurgical properties throughout every batch.

Our commitment to quality control ensures that every spool of ER-316/316L MIG & TIG wire undergoes rigorous testing to meet or exceed international specifications. Whether you require wire for general stainless steel fabrication or specialized chemical processing equipment, Metals And Welding Specialities delivers reliable, high-performance welding consumables that uphold your project’s quality and longevity.

For optimal results, use ER316/316H filler wire with argon or argon-based shielding gases to ensure smooth, stable arcs and superior penetration. Its unique metallurgical composition prevents dilution effects that typically reduce strength in mixed-metal welds. When durability, safety, and performance are non-negotiable, ER-316/316L stands as a dependable solution engineered to exceed expectations in demanding welding environments.
