DAIKOWT 309LMo
GTAW
- AUSTENITIC STAINLESS STEELS
309LMo
Description
Rod with 23% Cr – 13% Ni – 2.5% Mo
Rod primarily used in high dilution conditions, especially for welding dissimilar joints between duplex steels, stainless steels, and low-alloy steels. It provides excellent wettability and crack resistance characteristics. It is ideal for overlay welding of unalloyed and low-alloy steels, as well as for joining dissimilar steels such as 316L to unalloyed and low-alloy steels, where the presence of molybdenum is essential. Suitable for service temperatures between -40 °C and +300 °C.
