ESAB OK Tigrod 13.17 TIG Welding Rod
The ESAB OK Tigrod 13.17 is a premium copper-coated, low-alloyed TIG welding rod designed for welding creep-resistant steels. It contains 2.5% Chromium and 1.1% Molybdenum, making it suitable for materials such as SA-387 Grade 22 and A335 Grade P22. Its high purity, combined with a guaranteed Bruscato factor (X-bar < 15), ensures excellent performance in high-temperature applications. In addition, this rod is typically used in industries where post-weld heat treatment (PWHT) is required, with stress relieving typically performed at 600-700°C.
