Aditya Stainless, a top-notch manufacturer and supplier located in Kolkata, India, specializes in high-quality 309LMo MIG and TIG filler welding wire and rod. These products are specifically designed for high-performance welding in environments that are both highly corrosive and high-temperature. With enhanced resistance to pitting, crevice corrosion, and thermal fatigue, 309LMo is perfect for welding stainless steel and different types of metals. Aditya Stainless maintains strict quality control and precision alloying to ensure consistent mechanical properties, smooth feeding, and excellent arc stability. These filler materials find extensive use in industries like chemical processing, offshore operations, pulp & paper, and pressure vessels, where strength and corrosion resistance are crucial.
Aditya Stainless’s 309LMo MIG & TIG filler wire and rod consist of 23–25% chromium, 12–14% nickel, and 2–3% molybdenum, all while keeping carbon content low to minimize carbide precipitation. The inclusion of molybdenum significantly boosts resistance to pitting and crevice corrosion, especially in chloride-rich and acidic settings. With typical tensile strength ranging from 550–620 MPa, these fillers also offer excellent ductility and oxidation resistance. They create stable, crack-resistant welds and maintain sound metallurgical integrity even under high-temperature conditions. This makes them particularly effective for buffer layers, cladding, and joining dissimilar metals.
