PWHT of thin 2.25Cr-1Mo parts
PWHT of thin 2.25Cr-1Mo parts
(OP)
Hi all, I have come across a spec that requires PWHT based on material grades (P-Nos), regardless of thickness. This is likely to give distortion problems when welding thin components (1/8in or similar) made of F22. On the other hand, we risk failing the hardness test, if we try to qualify procedures for F22 without PWHT.
Can anyone share their thoughts?
