Aditya Stainless stands out as a top manufacturer and supplier in Kolkata, India, providing high-quality AWS Class ER308LSi MIG and TIG Filler Welding Wire and Rod. This product is specifically crafted for welding 304 and 304L austenitic stainless steels. With a higher silicon content, it enhances arc stability, improves wetting action, and gives welds a beautiful finish—perfect for those important fabrication projects. Its low carbon content boosts resistance to intergranular corrosion, especially post-welding. ER308LSi is a go-to choice in food processing equipment, piping systems, architectural structures, and chemical processing plants, delivering outstanding corrosion resistance and mechanical performance.
ER308LSi typically comprises 19–21% chromium, 9–11% nickel, ≤ 0.03% carbon, and 0.65–1.0% silicon. The increased silicon content improves the fluidity of the weld puddle, resulting in smooth, even weld beads with minimal spatter. Its mechanical properties include a tensile strength of at least 80,000 psi (550 MPa), yield strength of at least 55,000 psi (380 MPa), and an elongation of around 30%. The low carbon level helps prevent carbide precipitation, ensuring corrosion resistance in welded joints. ER308LSi is versatile for both MIG and TIG processes, providing reliable arc performance and making welding easier for both manual and automated applications.
