material selection for 100% hydrogen peroxide @ 90¦F
(OP)
Would 304L SS be a good choice of material selection for a tank and pipe containing 100% hydrogen peroxide @ 90°F for a service life of 20 years minimum? Do you have other recommendations that would last as long and be less expensive?
Thank you!

How much of a corrosion allowance should we allow for aluminium?
Thanks again!

Crevices mentioned above are associated with weld undercut and lack of penetration. Beveling the plate to butt weld will assure a full penetration weld and reduce the formation of crevices.
Purge gas is used for the GTAW process because the filler metal being deposited is bare wire so you need to protect the weld puddle. For the shielded metal arc welding (SMAW) process, the electrode contains a flux, so it is self shielding.

None taken. It all depends on the welder's skill and experience with aluminum. I did not want to lock in on any one process. I have seen some weel done girth and seam welds that were open root butt welds in aluminium tanks and vessels with SMAW.
