AF2209-16 (AWS E2209-16) is a calcium-titanium coated, nitrogen-containing, ultra-low carbon duplex stainless steel electrode. AWS E2209-16 Stainless Steel Welding Rod is designed for high-performance welding applications to ensure strong, corrosion-resistant joints in harsh environments.
AWS E2209-16 Stainless Steel Welding Rod is designed for joining duplex stainless steel and is suitable for industries that require durability and resistance to harsh conditions. Key application areas include chemical processing equipment, offshore structures, oil and gas pipelines, and pulp and paper systems. AWS E2209-16 Stainless Steel Welding Rod performs well in chloride-rich environments, acidic solutions, and high temperatures, making it an ideal choice for projects that require long-term structural integrity.
AWS E2209-16 Stainless Steel Welding Rod adopts ultra-low carbon composition, combined with nitrogen strengthening process, which can minimize carbide precipitation during welding, significantly reduce the risk of intergranular corrosion, and ensure that the welded joint maintains mechanical strength and chemical stability for a long time. The addition of nitrogen further enhances resistance to pitting corrosion, critical for components submerged in seawater or exposed to corrosive industrial chemicals. The AWS E2209-16 Stainless Steel Welding Rod’s smooth, stable arc reduces spatter and simplifies cleanup, while the calcium-titanium coating helps remove slag easily and creates a uniform weld bead appearance.
The unique design of the AWS E2209-16 Stainless Steel Welding Rod is compatible with both AC and DC power sources, providing flexibility in a variety of working conditions. High adaptability is suitable for vertical welding, horizontal welding and flat welding, and can meet complex manufacturing needs without affecting welding quality. The Rapid Solidification Slag System provides precise control of the weld pool even in challenging overhead or shallow angle welding conditions.
AWS E2209-16 Stainless Steel Welding Rod has excellent toughness and impact resistance at sub-zero temperatures, ensuring reliability in cryogenic applications. The balanced duplex structure of the weld metal effectively resists stress corrosion cracking, a common failure point for conventional stainless steels under cyclic loading. The low hydrogen content of AWS E2209-16 Stainless Steel Welding Rod reduces the risk of cold cracking, enhances the safety of high-pressure or high-vibration facilities, and is the first choice for infrastructure projects that require decades of maintenance-free operation.
