What is AWS Class ER347 SAW & Flux?
AWS Class ER347 SAW (Submerged Arc Welding) wire is a stainless steel electrode designed for welding 347-grade materials. Its typical composition includes 18–20% chromium, 9–12% nickel, 0.5–1.0% niobium, and low carbon content to enhance corrosion resistance and prevent sensitization. The matching flux ensures stable arc performance and deep penetration. Mechanical properties of ER347 welds typically include tensile strength of 550–750 MPa, yield strength around 275–450 MPa, and elongation of 35–45%. This combination provides excellent high-temperature strength, oxidation resistance, and durability for demanding industrial applications.

AWS Class ER347 SAW & Flux Uses
AWS Class ER347 SAW wire and flux are widely used for welding austenitic stainless steels, particularly in environments requiring high corrosion and heat resistance. Common applications include chemical processing equipment, pressure vessels, heat exchangers, boilers, and piping systems exposed to high temperatures or corrosive conditions. The wire-flux combination ensures strong, durable welds with excellent resistance to intergranular corrosion. Industries such as petrochemical, power generation, food processing, and marine engineering rely on ER347 SAW for critical structural and process components. Its reliability and high mechanical performance make it ideal for both fabrication and repair of stainless steel structures.
