I would like to know the P group for the high strength low alloy steel plate A 543 Type B Class 1.
Understand that PWHT is not required for this group as per ASME V111 Div. 1
Regular:
P No. for SA-543 Type B Class 1 "P11A, Group 5" with nominal composition of 3Ni, 1.75Cr, 0.5Mo. Minimum Tenslie Strength of 105 KSI. Not sure about the PWHT. Good Luck
