Dear Friends,

 

minimum PWHT Soaking temperature is given in ASME Sec VIII Div. 1 UCS-56, My question is What is maximum temperature that we can use for PWHT with reference to some applicable standards or metallurgical point of view point?

 

OR

 

Can we do PWHT for P.No.1 Gr.1 & 2 (e.g SA 516 Gr. 60 & 70) maximum up to lower critical temperature i.e. 723 Degree Centigrade?

 

Thanks in Advance for your valuable share.
