Hi
We had successfully welded and qualified a procedure to weld ASTM A473 Type 431,UNS:S43100 forging.
We had welded with SMAW:E309L.
Preheat and interpass was 250 degree C.
After completion of welding wrap in glass wool/asbestos for slow cooling.
No PWHT required.

>if you are referring to 431(UNS S43100) stainless, can be welded with AWS E/ER410.To avoid cracking, pre-heat the workpiece to 400-600 F (204-316 C). After air cooling, treat at 1200 F (649 C) to reattain maximum properties.
