ASTM - Material Groups

ASTM group tables list metals by group, such as forgings, castings or sheets. Metals in the same row of a table must have the same chemical‎‏ composition.

Corresponding materials listed in Section II of ASME‎‏ BPVC may be used provided that the requirements of the ASME specification are identical to or more stringent than the ASTM specification for the species, class or type of material.

General notes:

For temperature limitations, see notes in ASME B16.5 Tables II-2-1.1 through II-2-3.17 of Mandatory Appendix II.
Plate materials are listed only for use as blind flanges and reducing flanges without hubs (ASME B16.5 see para. 5.1). Additional plate materials listed in ASME B16.34 may also be used with corresponding B16.34, Standard Class ratings.
ASME Boiler and Pressure Vessel Code, Section II materials may also be used, provided the requirements of the ASME specification are identical to or more stringent than the corresponding ASTM specification for the Grade, Class, or Type listed.
