DAIKOWT 309LMo
GTAW
- AUSTENITIC STAINLESS STEELS
309LMo
Description
23%Cr – 13%Ni – 2,5%Mo solid rod
Mainly used under high dilution conditions, particularly for welding dissimilar joints between duplex and stainless
steels with low-alloyed steels. Very good wetting characteristics and high
resistance against cracking. Suitable for overlay welding of unalloyed and low alloyed steels and for welding of dissimilar steels such as 316L to unalloyed and low alloyed steels when Mo is essential. Suitable for service temperatures between –40°C and 300°C. There are no comparable base materials.
