Depends on which ASME Code you work with.
From the material type, I would guess you're working with pressure vessels?
If you look just under the title of "almost" every ASME steel specification (or filler metal specification), you will likely find the words that say: "Identical with, or similar to ASTM XXXXX" the XXXXX intended to represent a material specification, in this case A516. In most instances, ASME has licensing arrangements with ASTM and AWS to use those material specifications. In the case of AWS, the SFA's are taken directly from AWS A5-XX and reviewed and either adopted as is or modifed. If changes are made to either filler or base metal specification it is noted under the specification title.
That said, there are some ASME Constructing codes that require ONLY ASME materials are permitted; i.e., A516, 70 would not be permitted while SA516, Gr. 70 would be. I suggest you read the code you construct to in order to determine what your specific case is.
Look at QW420.2. Below is part of the text.
...... However, if procedure qualification testing was done using material assigned an S-Number or S-Number Group Number, the range qualified is limited to materials that are assigned S-Numbers or S-Numbers Group Numbers (i.e., qualification using a P-Number material qualifies corresponding S-Number materials; qualification using an S-Number material qualifies corresponding S-Number materials but not corresponding P-Number materials; ....
Hi @jon20013,
The PQR and WPS are following ASME IX as tittle of the topic. We don't need to mention the applicable code for fabrication, we just know applicable code for PQR and WPS qualification.
Hi all,
Thank you very much for you all answer, Pipewelder_1999 have very good answer, I think so also... Actually my jobs is Pressure Vessel and I found this comments from AI Inspector and I want to introduce to you all for this matters.
Thank you very much.....!
ASME IX is modified by the constructing code, as I mentioned, some ASME Codes permit ASTM materials, other ASME Codes REQUIRE SA Materials. ASME IX qualification by itself is okay for qualification but implementation must look to the constructing code requirements so without knowing the constructing code, your question cannot be properly answered.
My question is just follow ASME IX only, for example we do not have project specification or constructing codes, and even if some ASME codes permit ASTM materials but it is for fabrication not for procedures.
Then the simple answer is yes, you may use either A516, Gr. 70 or SA516, Gr. 70
Thank you very much.
Any others advice?
Look for S-number materials to become P-number materials in an upcoming revision. There will be no more separation of S-numbers and P-numbers.
What revision, I have read latest ASME IX revision but it is the same older revision.
I think it is upcoming. Along with some changes to P-Numbers for some materials from what I have heard.
Should be in 2009 Addenda.
