Well. We have to use an existing high pressure 1/8" OD tubing material. Thus far only 304, and Copper are the only options. So we have to solve the embrittlemnt problem, rather than sidestep it. Pretty sure this was solved during the Apollo era. Be nice to find a greybeard who remembers.

Looking for a process to minimize hydrogen embrittlement in small diameter tubing. Black oxide, nitiding, um thin plating, CVD etc. The coating process must survive tube bending, and work in hot Hydrogen gas exposure.
Any suggestions accepted. Tubing can be stainless, steel...
