Vinit Stainless, a reputable manufacturer and supplier located in Chennai, India, specializes in high-performance AWS Class E309/309L-16 electrodes. These electrodes are specifically crafted for welding dissimilar metals and stainless steels to mild or carbon steels. They boast impressive resistance to heat, oxidation, and corrosion, even in extreme temperatures. With meticulous alloying and rigorous quality control, Vinit Stainless guarantees smooth arc stability, minimal spatter, and clean weld profiles. Commonly utilized in fabrication, maintenance, and cladding tasks, the E309/309L-16 electrodes are perfect for critical operations in petrochemical plants, refineries, power plants, and structural engineering projects that demand durable, high-integrity welds.
Vinit Stainless’s AWS Class E309/309L-16 electrodes are made up of about 23–25% chromium and 12–14% nickel, featuring a low carbon content to reduce intergranular carbide precipitation. These electrodes deliver a typical tensile strength ranging from 550–620 MPa and exceptional ductility, ensuring dependable welds in high-temperature and corrosive settings. The low-carbon variant (309L) enhances resistance to sensitization and boosts long-term corrosion performance. The weld metal is resistant to oxidation and scaling, allowing for easy slag removal, a stable arc, and a finely rippled weld bead, making them ideal for multi-pass and positional welding.
