Other BPV sections do allow this material for code applications which is why it’s listed.

I don't understand the point of Line 3 with no Grade, UNS, or Diameter specified but I've never seen A-325 stud bolts used with pressure vessel flanges before. They are permitted in ASME Section VIII but I've only seen them used for anchor bolts or structural steel.

Christine, I wondered about that as well, My old (2009) SA-325 lists bolts of Type 1 and Type 3 (weathering steel) only. No "untyped" bolts. I wonder if this was added in a newer Edition?

The problem with sloppy work is that the supply FAR EXCEEDS the demand

@ Maritza Ulloa
Is it a curiosity or do you really want the SA-325 for nuclear service?
