Walid Stainless, located in Tunis, Tunisia, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel welding consumables. One of their standout products is the **AWS Class ER316LSi MIG and TIG filler wire and rod**, crafted to deliver exceptional corrosion resistance and outstanding weldability for austenitic stainless steels. This filler metal is known for its smooth arc performance, minimal spatter, and robust, crack-resistant weld deposits, making it perfect for both manual and automated MIG and TIG welding applications. Walid Stainless is committed to rigorous quality control and compliance with international standards, catering to various industries including chemical processing, marine, food and beverage, power generation, and construction.
The AWS Class ER316LSi MIG and TIG filler metals are low-carbon austenitic stainless steel consumables, primarily made up of iron, chromium (16–18%), nickel (10–14%), molybdenum (2–3%), and silicon (0.5–1%) added intentionally to enhance fluidity and wetting during the welding process. The low carbon content helps minimize the risk of intergranular corrosion, while silicon boosts arc stability and deposition. In terms of mechanical properties, the weld metal boasts a tensile strength of about 75 ksi (515 MPa) and an elongation of around 35%, ensuring excellent toughness and ductility for demanding applications.
