High Pressure Manifold Material (Brass vs. SS)
High Pressure Manifold Material (Brass vs. SS)
(OP)
Looking across the industry I find that high pressure bottle manifolds for hydrogen delivery are constructed from brass. Does anyone know of a reason why stainless steel can not be used in place of hydrogen? I've read some place that the removal of carbon from the steel creates voids into which the hydrogen diffuses and for some reason weakens it. Has anyone heard of this?

Brass is probably common due to its lower cost.

You can use ferritic stainless if hardness is kept below 100 Rb.
