Duplex Satinless Steel with CS
(OP)
We have to make weld between tube and tubesheet. Tubes material
SA-789 UNS S31803, tubesheet material is SA-516-70, welding process shall be GTAW.
Would ER309LMo be a good option? Any suggestion please?
Thanks for any favor.

ER2209 is used to weld duplex to duplex, we never used it to weld duplex to carbon steel. Do you have any experience?

We have used ER2594 to make the weld at the request of the Owner/
Operator (large Petrochemical company).

So far no problems but the weld has only been in service for a little over a year. Our "standard practice", when no direction is provided by the Owner/Engineer, is also to use ER309LMo depending on service temperature (normally service temps are below 350F).
