Aditya Stainless, located in Kolkata, India, has earned a solid reputation as a reliable manufacturer and supplier of top-notch welding consumables. Their offerings include the AWS Class ER316LSi MIG and TIG Filler Welding Wire and Rod, which are specially designed for superior weldability and corrosion resistance. This filler is perfect for joining molybdenum-bearing austenitic stainless steels like 316 and 316L. With its higher silicon content, it enhances arc stability and gives a polished look to weld beads, making it a go-to choice for precision fabrication. Aditya’s ER316LSi filler wires and rods adhere to strict quality standards and find applications in various industries, including food and beverage, pharmaceuticals, marine, petrochemical, and chemical processing.
ER316LSi is composed of about 18–20% chromium, 11–14% nickel, 2–3% molybdenum, and a higher silicon content (0.65–1.00%) that boosts wetting and bead appearance. Its low carbon content (≤0.03%) helps avoid carbide precipitation, ensuring outstanding intergranular corrosion resistance. The mechanical properties are impressive, featuring a tensile strength of at least 75,000 psi (520 MPa), a yield strength of at least 57,000 psi (390 MPa), and an elongation of around 30%. This filler metal is particularly resistant to pitting and crevice corrosion, especially in chloride-rich environments, making it ideal for applications that demand high integrity and cleanliness in welded joints.
