I am so tired of hearing all of the self professed experts on this board saying 6351-t6 are bad.
I found a old report from PSI, take a look at this

This is just the ones in the scuba industry, this does not include the industrial side, the medical O2 side, the carbon fiber wrap side, the paintball side or the CO2 side
All tanks fail!! Alum, steel, carbon fiber, 6351-T6 and the new 6061-T6 also FAIL
That is the job of the DOT Retester to try to ferret out the weak ones.
I will check with Mark at PSI tomorrow to see if they have a updated list and if they will release it to me.
