AWS Class ER347 is a stabilized austenitic stainless steel wire that contains chromium (19-21%), nickel (9-11%), and columbium (niobium), which helps improve resistance to intergranular corrosion. It usually has trace amounts of silicon, manganese, and carbon. In terms of mechanical properties, it boasts a tensile strength of about 80,000 psi (550 MPa), a yield strength of 55,000 psi (380 MPa), and a minimum elongation of 30%. The matching flux not only enhances the ease of slag removal but also improves the appearance of the weld bead, ensuring consistent weld integrity. This powerful combination offers excellent weldability, high strength, and thermal stability, making it ideal for high-temperature and corrosive environments.

AWS Class ER347 SAW and FLUX Uses

The AWS Class ER347 SAW and its associated flux are popular choices for applications that demand excellent corrosion resistance and stability in high-temperature environments. You’ll often find this filler material in industries like petrochemical, food processing, pharmaceuticals, and power generation, where it shines in welding 321 and 347 stainless steels. It’s particularly well-suited for pressure vessels, piping systems, and heat exchangers that operate under elevated temperatures. Plus, the addition of niobium helps stabilize the weld against carbide precipitation, making it a great fit for areas that are susceptible to intergranular corrosion. Its compatibility with Submerged Arc Welding (SAW) guarantees deep penetration and smooth, high-quality welds, perfect for heavy-duty fabrications.
