(OP)
I've been looking through Sect.11 Pt.D but can't seem to locate the stresses for ASME SA 570 Gr.B plate. Can someone point me in the right direction?
Thanks!
Thanks!

RE: ASME SA 570 Gr.B
I also checked several resources on plate specifications - I found nothing on SA 570. What is your specific application?
RE: ASME SA 570 Gr.B
I'm trying to develop a table of plate thickness values (tmin)for air receivers. I was told the material was SA 570 Gr.B but I have not been able to locate it either. Based on your response I may have the incorrect material spec. I'll double check and post back.
Thanks for your quick response, it's appreciated since I'm trying to take care of this today.
RE: ASME SA 570 Gr.B
I was looking for SA516 Gr.70, thanks for your assistance. Sorry for posting the wrong spec.

RE: ASME SA 570 Gr.B
Is A570 a material that is typically used in the fabrication of air receivers? If so can you tell me where to find it in Section 2 Part D.
Thanks in advance.

That's where I was going with my previous post.
I just wanted to make sure that I had not overlooked the material in Sect. 2 Pt. D.
I take it that the "A" designation ie. A 570, is not a material that I would find in Sect. 2 Pt. D and as such is not suitable for PV fabrication as you stated?

How do we edit a posting?
RE: ASME SA 570 Gr.B
In the case of the material you mentioned... SA516-Grade 70 is the ASME designation. A516-Grade 70 would be the ASTM designation.

Ordering by the ASTM Standard insures you have everything needed to insure that is what you order is what you get. You don't gain anything by ordering to an ASME designation as the manufacturing, ordering and tracking standards is to ASTM or it's equivalent depending on location.

Over the years, ASTM and ASME have been working very closely to bridge this gap - thus the issuance of Appendix A. This appendix has helped to allow the use of ASTM material specifications in Code construction. As stated in Section II and in Apendix A..."materials for Code use should preferably be ordered, produced and documented on this basis (meaning SA material specifications).....
RE: ASME SA 570 Gr.B
The Forward and UG-4 gives you some options-be careful,if Sec II lists ASTM 96 and the steel is made to ASTM 03 it may not be the same. It is up to the Manuf. to assure the AI that the ASTM requirements of a piece of steel,the paperwork,and the steel will meet all the requirments of the SA spec.
Record a statement on the MTR ie:Meets requirements of****. The Manuf. must sign and date. Then beg the AI to sign(Ha-Ha).
You have some latitude if your ducks are in a row.
RE: ASME SA 570 Gr.B
that was my point: sell it to the AI, some of them will not buy it and argument begins, who needs that,

ASTM 03 was a committee on gray iron castings and was merged into ASTM 04 Iron Castings.
ASTM A3 is a standard for railroad splice bars and is still good in force.
ASTM A96 was withdrawn in 1965 and was a standard for high temperature bolting.
As you state order materials by both standards as you will find most suppliers don’t keep ASME section II on hand. Most have the ASTM compilations of standards for fasteners or of chemical processing materials.
Additionally I have check the last 100 orders at a bolt distributor and found only 3 orders for fasteners that call out SA 193 B7, et all. All the other orders specify ASTM standards for the fastener materials.
My canvas only included people who would be concerned with needing ASME code materials and flagged as such on the order system.
At a sister piping distributer the sales manager stated that the orders run about 20% for SA materials and the rest are ASTM.
One thing to note is on MTR's is the occasional use of the word "typical". Usually in small print at the header. The fastener people have actually have been ask to pay for the actual MTR.
