Lecong Stainless Manufacturer and Suppliers in Da Nang, Vietnam, supplies AWS Class ER347 SAW wire and flux, intended for welding stabilized austenitic stainless steels. This wire contains niobium, which stabilizes the weld deposit and prevents carbide precipitation, improving resistance to intergranular corrosion. It is particularly suited for high-temperature and corrosive environments. When used with suitable flux, ER347 provides stable arc performance, high deposition efficiency, and good slag detachability. Lecong Stainless supplies ER347 SAW and flux solutions to various industries across Vietnam and internationally, ensuring durable, reliable welds for critical fabrication and maintenance tasks.
ER347 SAW wire usually contains 19–21% chromium, 9–11% nickel, and niobium as a stabilizer. The addition of niobium prevents carbide precipitation during welding, maintaining resistance to intergranular corrosion. Mechanical properties include a tensile strength of around 80,000 psi, a yield strength of about 55,000–60,000 psi, and an elongation of 30–35%. Weld deposits demonstrate toughness, creep strength, and excellent corrosion resistance in high-temperature situations. With optimized flux, ER347 provides smooth beads, stable arc performance, and durable welds, making it suitable for submerged arc welding in demanding industries.
