Re: [MW:16718] Material P and S numbers from API and ASME

Please note that there are no  more S numbers in ASME IX. You can use your PQR for welding any P1 material (if CVN impact test is not required). API 5L X60 is assigned as P1 material.

However additional restrictions from your code of construction will also apply. for e.g. ASME B31.3 requires a qualified WPS is required for each strength level of this material.

Dear experts,

As far as I know refering QW-420.2 Asme sec9, when we qualify P1toP1 or P1toS1 it will qualify all P1toP1, P1toS1 and S1toS1
But welding S1toS1 will only qualify S1toS1 materials, is that right?

My question is can we make a WPS from p1g1 to p1g2 PQR to weld for exmpl. API 5L X60 material?

I found different sources that claims x60 as S1 mat or P1 material.

Regards,
