The P-number for Duplex (UNS 31803) is 10H, and the P-number for 316L is 8. That would require requalification.

Hey, Chuck! Glad to see you back in! Was wondering if you got any of the fallout from Katrina?

Hi Jon,
No, here in Dallas we are still high and dry. Glad it missed us, but we still need rain very desperately.

I agree with requalification according to ASME sec.IX because the base metal is essential variable and when change the base metal you need to qualification.
