Is there a brass typically used for parts designed per ASME B31.3 ?

Is there a brass typically used for parts designed per ASME B31.3 ?

Is there a brass typically used for parts designed per ASME B31.3 ?

(OP)
I am designing a pressure bound part per ASME B31.3.  I would like to use brass per spec ASTM B453, but this does not appear in the "listed" specifications.  The part will be used at elevated (250F) applications, so I will need temperature dependant stress data.

Is there a typical brass selected for use?  There are many alloys available in the SB-98 and SB-150 specs approved for VIII, so I am wondering if one of these is typically used over the other (or if there is something completely different typically used).


Thanks.

Look at Table A-1 of ASME B31.3 and under Copper and Copper Alloy Forgings you have ASTM B283, several brass alloys to work with and have stress lines.

Unfortunately, I need a bar stock specification for my application.  These seem to not be included in table A-1 of B31.3, so I have turned to VIII specificaitons.

Be warned that you need to make sure the allowable stress values are the same or more conservative in comparison to the requirements for allowable stress values in B31.3....

323.1.2 Unlisted Materials. Unlisted materials may
be used provided they conform to a published specification
covering chemistry, physical and mechanical properties,
method and process of manufacture, heat
treatment, and quality control, and otherwise meet the
requirements of this Code. Allowable stresses shall be
determined in accordance with the applicable allowable
stress basis of this Code or a more conservative basis.

See 302.3.2
