ER316LSi MIG & TIG Welding Wire

At Metals And Welding Specialities, we supply high-quality AWS Class ER316LSi stainless steel welding wire designed for superior performance in both MIG and TIG applications. Engineered for precision and reliability, this filler metal meets the demands of industries requiring excellent corrosion resistance, consistent weld quality, and smooth feedability. The ER316LSi wire is manufactured to the highest standards, offering low carbon content and enhanced silicon levels for improved arc stability and wetting characteristics.

This product conforms to UNS S31683, ASTM A240 / A276 Grade 316L, and the universal standard AWS A5.9 ER316LSi, ensuring compatibility and consistency across a wide range of fabrication requirements. It is specifically designed for joining 316L and 316 stainless steels, as well as dissimilar steels where corrosion resistance is crucial. Thanks to its low carbon formulation, the risk of carbide precipitation during welding is minimized, making it ideal for applications exposed to corrosive environments such as chemical processing plants, food and beverage production facilities, and marine structures.

The added silicon in ER316LSi enhances the fluidity of the molten weld pool, resulting in a cleaner, more uniform bead appearance. This property is particularly valuable in GMAW (Gas Metal Arc Welding) and GTAW (Gas Tungsten Arc Welding) processes where aesthetic quality and consistency are critical. Whether used for manual, semi-automatic, or robotic welding operations, ER316LSi wire delivers excellent mechanical properties and resistance to intergranular corrosion.

Metals And Welding Specialities ensures every spool of ER316LSi stainless steel filler wire undergoes strict quality inspection for chemical composition and surface finish. Our wire offers optimal feedability, stable arc characteristics, and minimal spatter, resulting in reduced cleanup time and higher productivity. It performs exceptionally well on austenitic stainless steels, maintaining tensile strength and toughness even in elevated temperatures or cryogenic conditions.

Commonly used across petrochemical, pharmaceutical, pulp and paper, and offshore industries, AWS Class ER316LSi provides the ideal combination of durability, corrosion resistance, and weldability. For manufacturers and fabricators seeking a dependable welding solution that meets both performance and compliance standards, Metals And Welding Specialities delivers unmatched quality backed by technical expertise and reliable supply.
