PWHT of 321 SS
PWHT of 321 SS
(OP)
Hello,
I have recently had a request to prepare a WPS/PQR for welding 321 SS. My question is at what service temperature would this material require a sensitization PWHT? For example, the part we are fabricating will never see a service temp over 450 F.
Thanks in advance.

I was given a guideline of 800 F, which sounded a bit low to me, eventhough we're nowhere near 800 F.
