Hi...Megnath,
I could not understand why TPI needs a separate WPS for rolled plates and forged material, eventhough both are with same grade. If any properties changes with forging and rolling that will not be denoted with same grade number. If you have a MTC for the both material please match it for tensile trength and chemical composition.
In ASME sec IX manufacturing process of material is not a variable.
