Adam Stainless, located in Canberra, Australia, is a well-respected manufacturer and supplier of top-notch welding consumables, including AWS Class ER347 submerged arc welding (SAW) wires and flux. They’ve built a solid reputation for delivering high-quality and consistent welding products that adhere to strict industry standards. Their ER347 SAW wires and flux are specifically designed to offer outstanding corrosion resistance and mechanical strength, making them perfect for demanding stainless steel welding tasks across various Australian industries.
The AWS Class ER347 SAW wires are made up of about 18-20% chromium and 9-13% nickel, with niobium (columbium) added to prevent issues like carbide precipitation and intergranular corrosion. This unique blend results in impressive tensile strengths of around 75 ksi, along with good ductility and toughness. The accompanying flux is crafted to ensure a stable arc performance, easy slag removal, and top-notch weld bead quality during submerged arc welding.

Alloy ER347 SAW and Flux are used for submerged arc welding of stainless steel, offering high resistance to intergranular corrosion, excellent strength, and a clean, slag-free weld for high-temperature applications.
AWS A5.9 ER347 SAW and Flux Welding Wire is designed for submerged arc welding of stainless steel, providing strong, durable welds with high resistance to intergranular corrosion and a clean, efficient finish.
AWS Class ER347 Submerged Arc Welding Flux provides excellent arc stability and a clean, slag-free weld. It enhances corrosion resistance and weld quality for high-temperature and stainless steel applications.
ER347 SAW wires and flux are commonly utilized in sectors like chemical processing, power generation, and marine industries, where resistance to intergranular corrosion and stability at high temperatures are crucial. They’re particularly well-suited for creating large stainless steel components such as pressure vessels, piping, and storage tanks that face corrosive environments. The combination of wire and flux allows for high deposition rates and consistent weld quality, making them ideal for heavy fabrication projects.
AWS Class ER347 is a filler metal used in gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW) for welding austenitic stainless steels, particularly for applications requiring high-temperature resistance. It’s commonly used in industries such as petrochemical, chemical and power generation. The flux in submerged arc welding (SAW) helps stabilize the arc, protect the weld pool from contamination, and improve weld quality. ER347 and flux combinations are ideal for welding applications in high-temperature, corrosive environments.
