BOEHLER Q T 309L TIG Rod

This document summarizes the characteristics of the BÖHLER Q T 309L TIG rod for welding dissimilar joints. It is a high-alloyed, austenitic stainless steel rod well-suited for depositing intermediate layers when welding cladded materials with an average ferrite content above 10 FN. It is suitable for service temperatures between -80°C and 300°C for surfacing unalloyed/low-alloyed steels and joining non-molybdenum stainless/carbon steels. Typical mechanical properties of the all-weld metal are provided.
