RE: Plate Material best suited for H2S applications
I dont have copy of NACE TM 0284 - Does it specify any ASTM material for H2S corrosion for pressure vessels?

ASTM A516 Gr 70 is a good, low carbon, fine grain all around choice. ASTM 515 Gr 70 and ASTM A285 are also possibles too but A516 is generally stronger and has a finer grain which is good for toughness. A515 is coarser grained and that is good for high temp creep. All three are intended for pressure vessel service.
All of the above however have around .15 to .30 silicon in them though and I can't recall off the top of my head what the NACE MR0175 limits are for silicon, that might take them out of the running.

I've purchase pure (well, 99.5%) H2S (liquified gas) for research; it came in aluminum gas cylinders.

Excellent tip Rorsachach. Thanks a lot . In fact I have come across ASTM 516 Gr 70 many times but still was not sure to substantiate the selection.
Thanks a lot for the practical tip

For more severe H2S environments gunite lining, stainless steel clad plate, etc. may be required.
