Aditya Stainless, a reputable manufacturer and supplier located in Kolkata, India, specializes in high-quality AWS Class ER309/309L MIG and TIG Filler Welding Wire and Rod. These products are perfect for joining dissimilar metals and austenitic stainless steels. With a higher content of chromium and nickel, ER309/309L offers outstanding resistance to oxidation and corrosion, even in high-temperature settings. The low carbon content in the “L” variant helps prevent intergranular corrosion, particularly during high-temperature applications. These filler materials ensure smooth arc characteristics and reliable weld performance, making them ideal for critical fabrication tasks in chemical processing, heat exchangers, furnace components, and structural welding.
ER309/309L is composed of about 22–24% chromium, 12–14% nickel, and a maximum carbon content of 0.03% in the low-carbon “L” version. This specific blend provides remarkable oxidation and scaling resistance, especially under high-temperature conditions. Typical mechanical properties include a tensile strength of at least 80,000 psi (550 MPa), yield strength of at least 55,000 psi (380 MPa), and an elongation of around 30%. The low carbon content helps prevent carbide precipitation, which enhances corrosion resistance post-welding. ER309/309L ensures a stable arc, minimal spatter, and smooth weld beads, making it suitable for both manual and automated MIG/TIG welding processes.
