Aditya Stainless, a reputable manufacturer and supplier located in Kolkata, India, specializes in high-performance AWS Class ER309/309L Submerged Arc Welding (SAW) Wire and Flux, perfect for critical fabrication and joining tasks. These filler materials are specifically designed for welding dissimilar metals and for overlaying carbon or low-alloy steels with stainless steel. With a low carbon content to help prevent intergranular corrosion, the ER309/309L wire, when used with the right flux, guarantees stable arc characteristics, a smooth bead finish, and outstanding mechanical properties. Aditya Stainless is committed to providing dependable and consistent welding consumables that adhere to international standards, catering to industries like chemical processing, shipbuilding, and structural engineering both in India and abroad.
AWS Class ER309/309L SAW Wire features a composition of 23–25% chromium and 12–14% nickel, along with a low carbon content (≤0.03%) to reduce carbide precipitation and enhance intergranular corrosion resistance. When paired with the appropriate flux, this wire produces a robust, ductile, austenitic weld deposit that boasts excellent crack resistance. The typical tensile strength ranges from 550 to 650 MPa, with a yield strength of around 350 MPa and an elongation of about 30%. The flux ensures easy slag removal, a pleasing bead appearance, and stable arc performance. ER309/309L is particularly well-suited for joining stainless steel to carbon steel and for applications requiring corrosion-resistant overlays.
