The E347-16 welding electrodes are stabilized with niobium and columbium, ensuring outstanding resistance to chromium carbide precipitation at elevated temperatures. This makes them ideal for joining stainless steels exposed to high-temperature service. The advanced formulation of 347 electrodes ensures smooth arc performance, minimal spatter, and strong mechanical properties, making them suitable for both structural and fabrication work in critical industries.
Metals And Welding Specialities’ UNS S34700 electrodes are widely used in industries such as chemical processing, petrochemical, pharmaceutical, power generation, and food processing. These electrodes perform exceptionally in environments containing organic acids, nitric acid, and other oxidizing conditions. The weld deposits provide high toughness and maintain mechanical strength even under severe thermal cycling. With high resistance to stress corrosion cracking and excellent oxidation resistance, these electrodes are well-suited for welding components that demand long service life and reliable performance.
The AWS Class E347H coated electrode is a universal standard welding solution, compatible with stainless steels of similar composition. It delivers crack-free, durable welds and can be used in both flat and horizontal welding positions. Its coating ensures superior arc stability, easy slag removal, and enhanced weld bead appearance, reducing rework and boosting productivity. Metals And Welding Specialities ensures that every electrode supplied meets stringent international quality standards, providing customers with products they can trust for critical applications.
Customers searching for reliable stainless steel welding solutions will find that ASTM A240 Grade 347 electrodes offer unmatched performance where resistance to intergranular corrosion and high-temperature scaling is essential. Whether used in pressure vessels, heat exchangers, boilers, or piping systems, Metals And Welding Specialities provides welding electrodes that consistently deliver long-lasting results.
At Metals And Welding Specialities, we understand the importance of high-quality electrodes in welding applications. That is why our AWS E347-16 electrodes are produced using advanced technology and strict quality control, ensuring defect-free performance and uniformity in every batch. With excellent mechanical strength, ductility, and corrosion resistance, our electrodes are the preferred choice for industries worldwide.
