AWS/ASME 5.14 ER347 MIG & TIG Filler Wire Manufacturer in Kolkata SFA A5.9 ER347 MIG & TIG Filler Rod Supplier in India, Alloy ER347 Welding Mig & Tig Filler Wire Exporter in Kolkata, UNS S34780 Mig and Tig Stick Filler Metal Trader in Kolkata, AWS ER347 Mig & Tig Filler Metal Rod & Wire India AWS Class ER347 Metal Inert Gas (MIG) Welding Kolkata

Aditya Stainless, a well-respected manufacturer and supplier based in Kolkata, India, specializes in providing top-notch AWS Class ER347 MIG and TIG Filler Welding Wire and Rod. This product is designed for exceptional performance when welding stabilized austenitic stainless steels. The ER347 formulation includes columbium (niobium) as a stabilizing agent, which helps prevent intergranular corrosion and carbide precipitation during high-temperature welding. It boasts impressive weldability, arc stability, and resistance to oxidation and corrosion, making it perfect for challenging environments. This filler metal is particularly suited for joining 321 and 347 stainless steels and is commonly used in high-temperature and high-pressure settings like power plants, chemical processing, and aerospace fabrication.

ER347 is composed of roughly 19–21% chromium, 9–11% nickel, and ≤0.08% carbon, with columbium (Nb) added to stabilize the mixture—typically at eight times the carbon content. The inclusion of niobium significantly boosts resistance to intergranular corrosion and ensures stability under high-heat conditions. Its mechanical properties are impressive, featuring a tensile strength of at least 75,000 psi (520 MPa), yield strength of at least 55,000 psi (380 MPa), and an elongation of around 30%. This filler wire retains its excellent mechanical characteristics even after extended exposure to high temperatures, making it a dependable choice for pressure-retaining and thermally cycled components in demanding environments.
