Quick Answer: What Are Thermanit 310 TIG Rods?
Thermanit 310 TIG Rods are high-alloyed, austenitic, heat-resistant stainless steel filler rods used for joining and surfacing suitable heat-resistant steels and cast-steel grades. They are classified as ER310 under AWS A5.9 / SFA-5.9 and G 25 20 under EN ISO 14343-A. Selection should be based on the parent material, operating environment and qualified welding procedure.
Thermanit 310 TIG Rods – Product Overview
Thermanit 310 is designed for welding applications that require a high-alloyed, austenitic stainless steel filler metal with heat-resistant characteristics. Its chromium-nickel alloy composition makes it suitable for specified fabrication work involving matching or similar heat-resistant rolled, forged and cast-steel grades.
Typical application areas include annealing shops, hardening facilities, steam boiler construction, crude oil industry equipment and ceramic industry installations. The appropriate filler metal depends on the exact base-metal grade, gas atmosphere, operating temperature and fabrication specification.
Thermanit 310 may also be used for tough fill layers beneath cap passes in certain welding applications involving thicker chromium-steel sections, where the selected procedure is designed for service in sulfurous atmospheres. The complete welding procedure and cap-pass consumable selection must follow the manufacturer's recommendations.
