QW 422 ASME SEC IX
This table enlists P no Gr for specified materials .
For ASME SEC IX PQR ,only LISTED materials are permitted to take range of qualification.
Unlisted materials ( Not listed in QW 422 Table)need separate qualification.
For WPQ , the Welder qualification can be done on other NON ASME materials with matching chemistry , Strength with ASME Listed materials Pl speak to AI for WPQs for unlisted material for WPQ.Any Client permission . You may have to take or keep apprised about the same .
Thanks

Hello, dear friends. I hope this email finds all of you well.--Considering that there is a list of steels (and other metals) that are listed by the ASME BPVC Code, and also considering that there is a large list of steels produced that are not included in this official list, what are the steps to be taken to establish an equivalence and reclassify a steel such as Q235B (Chinese) to SA36 (I don't think it's only due to chemical composition and mechanical properties)Any help will be very much appreciated.
