What is the difference between A-36 & SA-36? 5

[m1gee]

Hey everyone!

Quick question: "What is the difference between A-36 and SA-36?" And are they equivalents?

Thanks in advance!

m1gee;
The difference is this; for any material certified as SA, this indicates that it is endorsed by the ASME Boiler and Pressure Vessel Code for use in pressure retaining items. For A designation material, this material is supplied under ASTM certification.

Now for the actual difference between ASME SA 36 and ASTM A36, there is none. They are considered identical, for other materials this may not be the case.

 

[JStephen]

ASME publishes their own standards for materials used in pressure vessels, although most of these standards are the same as other industry standards. SA-36 is the ASME standard for one type of plate, and it is based on ASTM A36. Generally, they are going to be the same. Sometimes ASME is based on an older version of ASTM and it's possible that ASME would have other requirements. For vessel work, you'd refer to SA-36, for structural and other uses, A36. Most of the time, plate that meets one standard will meet the other.

Additional information to the 2 before:
In ASME IIA, you can find a chapter "Acceptable ASTM editions" (page xlvii), giving details about the allowed ASTM grades in function of the design code and the acceptable editions. Not all editions are acceptable. E.g. up to Addenda 06, ASTM A516 edition 90 was acceptable and not the more recent editions 03, 05, 06. At my experience, this assures that the used ASTM edition is 100% identical to the current ASME edition. In the ASME material standard, you always find the indication, to which edition of ASTM it is identical. But the easiest way is, as said by JStephen, to stay with ASME grades when material is used for ASME applications.

Thank you for all your helpful replies!

One more question: Does anyone if there's a book that lists the comparison between all the ASTM, ASME, JIS, DIN (as well as other international standards) metals and their equivalents? And if so, where I can purchase this book?

Thanks in advance!

Yes. Go to the CASTI web site and find the following;

http://www.casti.ca/

CAST Metals Black Book on European Ferrous data. There are references to metals and world standards, with a nice comparison at the end of the book. There might be a lite version of this book to download for viewing.
