[MW:24415] PWHT

Dear all,
I have two queries:
MOC: P8Gr1(SS347 internal)
PWHT on job with LAS is at 705+/-10 degree C for 10 hrs.
Available PQR: 700 degree C for 8 hrs.
Can I support same PQR for welding of SS347 internal which will undergo PWHT at 705+/- 10 degree C along with LAS???

Impact: not applicable for SS.

Second query:
Interpretation of QW407.1 (b).

Regards,
Maulik
