ESAB OK AUTROD 13.20 SC (EB3- 21/4Cr 1Mo) Saw Wire

ESAB OK AUTROD 13.20 SC (EB3- 21/4Cr 1Mo) is a submerged arc welding (SAW) wire specifically engineered for welding applications that require high strength, corrosion resistance, and elevated temperature performance. Developed by ESAB, a global leader in welding and cutting solutions, this wire is designed to meet the demanding requirements of industries such as power generation, oil and gas, petrochemical, and pressure vessel fabrication. The designation "13.20 SC" indicates that this wire is suitable for SAW processes, which are commonly used for welding thick sections of carbon and low-alloy steels. SAW offers high deposition rates, deep penetration, and excellent weld quality, making it suitable for a variety of welding positions. ESAB OK AUTROD 13.20 SC features a composition containing 21% chromium, 4% molybdenum, and other alloying elements, providing enhanced resistance to corrosion, oxidation, and high-temperature creep. This makes it particularly well-suited for welding components exposed to aggressive environments, such as pressure vessels, boilers, and piping systems in power plants, refineries, and chemical processing facilities. The wire is engineered to deliver stable arc characteristics, smooth weld bead appearance, and minimal spatter, resulting in high-quality welds with excellent mechanical properties. It offers good slag detachability and easy slag removal, reducing post-weld cleaning time and improving productivity. ESAB OK AUTROD 13.20 SC wire is available in various diameters to accommodate different welding requirements and is supplied on large spools for extended welding operations without frequent spool changes. It is compatible with a wide range of SAW equipment, including automatic and semi-automatic welding systems.
