ER347 filler features 18–20% chromium, 11–14% nickel, with niobium stabilization and carbon less than 0.035%. Niobium binds carbon to create niobium carbide, stopping chromium carbide precipitation. Tensile strength is about 75–85 ksi (515–585 MPa), yield strength is 30–40 ksi (205–275 MPa), and elongation is 35–45%. Hardness remains moderate (Rockwell B80–90). This stabilization ensures thermal stability, resistance to intergranular corrosion, and maintained toughness after exposure to heat. Excellent weldability through MIG and TIG ensures consistent mechanical performance.

AWS Class ER347 MIG and TIG Filler Welding Wires and Rods Uses

AWS Class ER347 filler is suitable for welding 347, 321, and similar stabilized stainless steels used in chemical processing, marine, and food industry equipment. It’s commonly used in creating exhaust manifolds, heat exchangers, and engine components exposed to temperatures between 800–1,200 °F. In the Houston area, it’s utilized for automotive exhaust fabrication, petrochemical plants, and refinery piping systems that experience changing thermal cycles. ER347 filler helps prevent intergranular corrosion in welded components subjected to hot or cyclic conditions. It’s ideal for MIG and TIG welding in applications requiring dimensional stability and corrosion resistance.
