(OP)
I am looking at some old heat exchanger drawings. Flanges and nozzles use material ASTM SPEC A-181-3T CL. I. The drawings are old and this material could be ASTM SPEC A-181-37 CL. I. Can someone tell me more about this material? Where can I look up this spec?

RE: material spec

Hi,

I have a copy of SA-181 (93). It was identical to ASTM A-181-93. If you want a copy, give me your email address. Unfortunately I don't have any information prior to that. ASTM has a web site which lists outdated specs and you can purchase copies of them there.
