Where can I look to find the composition of steel used for ASTM A 53? 3

[Rjeffery]

Where can I look to find the composition of steel used to make ASTM A 53 and A 106 pipe? I have some old(er) pipe that I need to evaluate its in-service condition that may or may not be ASTM spec pipe... No records are available to me. I want to make sure that the steel I am using to calibrate my UT machine is close in acoustic properties as I can get.

Thanks for the help.

To get reliable information, you should obtain the documents from ASTM International:

http://www.astm.org

They cost $47 and $35, respectively.

If you can't/won't do this, then a random Google search provides some sites with some composition information.

Thank you CoryPad. I have both specifications in hard copy. The table(s) provide only max% of a few elements.

I am looking to have step wedges made at a local machine shop and I have asked them to make them out of the same steel as A 53 and A 106. Their reply was "OK, what grade of steel is that?" I am at a loss to answer that question...

Since these step wedges for calibration purposes, you can specify a similar steel for UT. As you know, there are various Grades of A 53 and A 106. What I would do is to have the shop order

ASTM A 29 1025 carbon steel, hot wrought or finished.

That is how general the composition requirements are. As long as you are not using an alloyed steel I don't see any major UT issues. Things like grain size may end up being more important.
