Red Brass (conductive) in H2, H2S atmosphere
Red Brass (conductive) in H2, H2S atmosphere
(OP)
I am trying to evaluate the use of Red Brass (UNS C23000) as a conductive material in a gas plant atmosphere that is 70% H2, 14% CH4, 5% C2H6, 3%C3H8, and has <50ppm of H2S.
I have found lots of information on mechanical stresses and corrosion and stressing/fracturing of the brass due to this type of environment. But was looking for direction on where to find information that relates to the surface condition (mainly electrical properties) due to the corrosion. Of particular interest would be data on rates of corrosion (and depth of penetration over time).
A side note: Any advice on Copper Graphite material use in this atmosphere?
Thanks!

Corrosion never sleeps, but it can be managed.

copper/Carbon may not work long term because as copper corrodes, the oxide may cause spalling. lead sheathing is a good idea, as is nickel or gold plating.
