SA material vs A material
SA material vs A material
(OP)
What is the difference in using say SA335 VS A335. Is there differnt documentation? I always thought the material and stress values were the same. I've been told that ASME Section 1 requires SA material to be specified rather than A material





RE: SA material vs A material
In some cases A and SA material designations can be equivalent, in other cases they may not be equivalent with material that is an A designation not even permitted for use in code fabrication. So, review ASME Section II, Part A Acceptable ASTM Editions.

I appreciate your response.

RE: SA material vs A material
Its usually far easier to just specify SA materials, but the Code does provide you some wiggle room. I'd suggest reading the section on Acceptable ASTM Editions starting on page xlvii of Section IIA. The key thing to note is the quote Materials for Code use should preferably be ordered, produced, and documented on this basis; however, material produced under an ASTM Specification may be used in lieu of the corresponding ASME Specification as listed in this Appendix...
A335 is on page l (that's Roman 50, not one). The material is identical with several exeptions.

"identical with exceptions" huh?
