Amer Stainless, located in Amman, Jordan, is a reliable source for top-notch stainless steel welding consumables, including the AWS Class ER309 and ER309L MIG and TIG filler wires and rods. These products are specifically designed for joining austenitic stainless steels and for welding stainless steel to carbon steel, ensuring strong, durable, and corrosion-resistant welds. Amer Stainless is committed to meeting international standards, providing consistent performance across various industries like chemical processing, petrochemical, food processing, and construction, where high-quality stainless steel welding is crucial.
The AWS Class ER309/309L welding wires and rods are mainly made of iron, chromium, and nickel, with ER309L having a lower carbon content to minimize sensitization and intergranular corrosion. These filler metals offer excellent mechanical strength, toughness, and ductility, along with smooth arc characteristics and uniform bead formation. They work well with both MIG (GMAW) and TIG (GTAW) welding processes, ensuring superior weldability, minimal spatter, and clean, visually appealing welds.
