Re: [MW:8724] PQR with simulation

Hi Asad

ASME sec VIII Div 1 - gives guidance for fabrication heat treatment.

But, for accepting materials you have to review the TC with respect to
ASME II , Part A, as per the requirement of SA 387 GR 12 CL2 The
heat treatment soaking time in TC to meet this spec and the
corresponding general spec in ASME Sec II, part A.

Thanks
