P and S Numbers Listing

[Weldingnoob]

I am trying to locate a list that correlates P and S numbers to the corresponding material. Can anyone point me in the right direction?

If you can find earlier editions of the ASME B&PV Code, Section IX, prior to 2007, Qw-422 contains S-No's for certain materials.

metengr,
2007 is the latest copy of ASME IX I have.
This lists S numbers.
Did ASME stop listing them after 2007 ?
Regards,
Kiwi

Yes, it was 2009 addendum. For the reason below, excerpt from 2010 Edition of Section IX;

In 2009, S-Numbers were removed from table
QW/QB-422. S-Numbers were assigned to materials that
were acceptable for use by the ASME B31 Code for
Pressure Piping, or by selected Boiler and Pressure Vessel
Code Cases, but which were not included within ASME
Boiler and Pressure Vessel Code Material Specifications
(Section II). Base metals previously assigned S-Numbers
were reassigned the corresponding P-Numbers or P-Numbers
plus Group Numbers.

S number was reassigned with P-number in QW-422 in 2009 Addenda, and S number listing was deleted in that Addenda.
