Aditya Stainless, a well-known manufacturer and supplier located in Kolkata, India, specializes in high-performance Alloy 309LMo SAW wire and flux designed for submerged arc welding. With a reputation for consistent quality and advanced metallurgical knowledge, Aditya Stainless offers welding solutions that excel in demanding applications involving stainless steel and dissimilar metal joining. Their 309LMo SAW wire and matching flux provide outstanding corrosion resistance, particularly in high-temperature and chloride-rich settings. Committed to quality control and customer satisfaction, Aditya Stainless serves industries like chemical processing, power generation, and marine fabrication by supplying reliable and efficient SAW consumables for critical welding tasks.
Alloy 309LMo SAW wire from Aditya Stainless is composed of chromium (23–25%), nickel (12–14%), molybdenum (~2.2%), and low carbon, which together provide excellent corrosion and oxidation resistance. The molybdenum content significantly boosts resistance to pitting and crevice corrosion, especially in acidic or chloride-rich conditions. When used with the right flux, it yields weld metal with a tensile strength of around 550 MPa (80,000 psi) and showcases impressive toughness and creep resistance at high temperatures. Additionally, the weld deposit maintains good ferrite control, minimizing the risk of hot cracking during the welding process.
