Difference between ASTM A/B and ASME SA/SB Materials
Difference between ASTM A/B and ASME SA/SB Materials
(OP)
Can anyone please elaborate on the differences between the ASTM and ASME material grades? I know that ASME SEC III calls for ASME material while ANSI B31 calls for ASTM.

In some cases it is changing an optional test to mandatory, or something like that.
Virtually all material certified as ASME also meets the ASTM specs, but it does not always go the other direction.
