Pressure vessel ASME code
Pressure vessel ASME code
(OP)
I recently came across a problem regarding material used in a pressure vessel. We have always used material specified to ASME SA249. Now I am being asked to supply material to SB691. Does this only apply to AL6XN material or to 316L also?

SB-691 Iron-Nickel-Chromium-Molybdenum Alloys (UNS N08366 and UNS N08367) Rod, Bar, and Wire
Per your question, you are therefore comparing Tubes with Rod/ Bar/ Wires.
The spec. for AL6XN Tubes is ASME SA-249 (spec. common for AL6XN & 316L welded tubes)
The spec. for SS316L Rod, Bar, and Wire is SA 479.
