Miginox 347 / Tiginox 347: Classification: Approvals

This document provides information about Miginox 347 and Tiginox 347 stainless steel alloy wires for gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). The wires are a 19Cr/9Ni/Nb stabilized stainless steel alloy that offers high resistance to intergranular corrosion and cracking up to 850°C. They are recommended for welding applications involving Cr-Ni steels at high temperatures, including boilers, gas turbines, and stainless steel tanks and pipes.
