Harshita Stainless, based in Delhi, India, stands out as a top manufacturer and supplier of high-quality stainless steel solutions, including Alloy 309LMo SAW (Submerged Arc Welding) wire and flux combinations. The company prides itself on its dedication to quality, innovation, and customer satisfaction, serving a wide array of industrial needs with materials that comply with both national and international standards. Clients in the chemical, petrochemical, and marine industries trust Harshita Stainless for their Alloy 309LMo SAW products, which are celebrated for their outstanding corrosion resistance, high-temperature strength, and dependable weld integrity.
Alloy 309LMo SAW wire is composed of about 23% Chromium, 13.5% Nickel, and 2.5% Molybdenum, which significantly boosts its resistance to corrosion, oxidation, and thermal stress. It boasts a tensile strength of roughly 550 MPa, a yield strength of 300 MPa, and an elongation of 35%, ensuring it remains structurally sound under pressure. When paired with compatible fluxes like Flux SFA 5.23/EN 760, the weld achieves low carbon pickup, excellent slag removal, and high integrity, making it perfect for challenging environments that involve high temperatures and aggressive chemicals.
