Dear Guys,
I am building a new spherical thank Material is SA537-Class1, wall thickness= 31 mmm.
According to ASME sec VIII div 2. PWHT not mandatory , but user want to perform PWHT.
Fabricator of plate said :
ASME-SA-537 ( 65mm and under),Code Requirements: Tensile Strength :485 – 620 MPA
Expected Value after PWHT : 400 – 530 MPA.
So, after PWHT the Tensile strenght can be under the Code requirement ( 400 < 485)
Is this permitted by code (ASME sec VIII div.2) ?
Thanks in advance !
