Aditya Stainless, a prominent manufacturer and supplier located in Kolkata, India, specializes in top-notch AWS Class E309/309H-16 electrodes, perfect for welding dissimilar metals and high-temperature stainless steel components. These electrodes are crafted using cutting-edge production methods and are subjected to rigorous quality checks to guarantee outstanding performance even in tough service conditions. Renowned for their remarkable arc stability, crack resistance, and oxidation resistance, Aditya Stainless’s E309/309H-16 electrodes find extensive application in fabrication, repair, and maintenance across the petrochemical, power, and refinery sectors. With dependable support and consistent product quality, Aditya Stainless has earned a reputation as a reliable provider of stainless steel welding solutions.
Aditya Stainless’s AWS Class E309/309H-16 electrodes are formulated with about 23–25% chromium and 12–14% nickel, while the “H” grade features a slightly elevated carbon content to enhance high-temperature strength. These electrodes deliver impressive tensile strength (approximately 570–620 MPa / 82,000–90,000 psi) along with good ductility. They create weld metal that exhibits strong resistance to oxidation, scaling, and thermal fatigue at high temperatures. The increased carbon level in the 309H variant boosts creep resistance while ensuring excellent weldability. These electrodes also provide smooth slag removal, stable arc characteristics, and a beautiful bead appearance in all-position welding.
