P number classifications are assigned to all materials used under the ASME code to reduce the number of welding and brazing procedure qualifications for welding materials.
Get your hands on an ASME Section IX to get a detailed explanation of all this stuff.
For Welding:
Steel and Steel Alloys are assigned P No. 1 thru P No. 11 including P No. 5A, 5B, ad 5C.
Aluminum and aluminum based alloys are assigned P No. 21 thru 25.
Copper and copper based alloys are assigned P No. 31 thru 35
Nickel and nickel based alloys are assigned P No. 41 thru 47
Titanium and titanium based alloys are assigned P No. 51 thru 53
Zirconium and zirconium alloys are assigned P No. 61 & 62.
Then there are separate P number classifications for Brazing procedures
