    material selection for 100% hydrogen peroxide @ 90¦F

    So if we use Aluminum pipe instead of 304L SS would we weld the pipe with just an Argon back purge for backing so that there would be no crevices on the ID of the pipe? How much of a corrosion allowance should we allow for aluminium? Thanks again! Weldmetal

    material selection for 100% hydrogen peroxide @ 90¦F

    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! Weldmetal
