Here is a web site that might be of interest to you for P-No's at no cost. This web site was from another post in ET;

http://www.pnumbers.com/

Otherwise, either ASME B&PV Code, Section IX or AWS B 2.1-2005

If you look up a given material in ASME Section II Part D, it will list the P number and sub group in the last 2 columns on the right. The attached web site link will also provide a generic description of what each P number group of materials are.
