Walid Stainless, located in Tunis, Tunisia, has earned a solid reputation as a reliable manufacturer and supplier of high-quality stainless steel welding consumables. One of their standout products is the **AWS Class ER317L MIG and TIG filler wire and rod**, crafted to offer exceptional corrosion resistance and top-notch weld quality for austenitic stainless steels, even in tough environments. This filler metal ensures smooth arc stability, minimal spatter, and robust, ductile weld deposits, making it perfect for both manual and automated MIG and TIG welding processes. Walid Stainless is committed to strict quality control and follows international standards, catering to industries like chemical processing, petrochemical, marine, power generation, and food and beverage, where reliability and corrosion resistance are absolutely essential.
The AWS Class ER317L MIG and TIG fillers are low-carbon austenitic stainless steel consumables, primarily made up of iron, chromium (18–20%), nickel (11–14%), and molybdenum (3–4%). The low carbon content (‘L’) helps reduce carbide precipitation, boosting resistance to intergranular corrosion in harsh environments. In terms of mechanical properties, the weld metal typically achieves a tensile strength of around 75 ksi (515 MPa) while offering good elongation and toughness, ensuring that the joints are durable and crack-resistant. The well-balanced alloy composition results in fully austenitic weld deposits that exhibit excellent ductility and corrosion performance.
