7075 Aluminum and ASME B31.3
7075 Aluminum and ASME B31.3
(OP)
Hi everyone,
I have a component fabricated from 6061-T6 Aluminum seamless tube, and a recent study found some limitations in it's internal design pressure at higher temperatures based upon calculations from the ASME B31.3 standard. We currently operate within those limitations, but this may change in the future.
I am currently investigated whether or not the same component can be fabricated from 7075 Aluminum instead. However, the basis for the calculations is Table A-1 in the B31.3 which gives basic allowable stresses for a variety of materials at different temperatures. In this table, 6061-T6 is listed, but 7075 is not.
Section 302.3.2 of B31.3 gives the basis for the numbers in Table A-1, and the ASM Handbook vol 2 gives some data on 7075, so given enough time, I could piece together a table of basic allowable stress at different temperatures for 7075. However, I'm wondering if I'm just re-inventing the wheel -- does anyone know of any published data for 7075 that has the allowable stress values already calculated.
Many thanks in advance

Just use the ones listed in MMPDS. You could go back to the people at Battle that maintain MMPDS and as for the raw data for the product forms that you are interested in.
