You don’t even need cracks. Helium (and hydrogen) can diffuse through metal, especially at high temperatures. Hydrogen embrittlement is a problem for processes that use high temp hiydrogen like the Haber process.

how is it typically dealt with? regular annealing?
I’m not sure about in modern processes, but Bosch’s original solution for the Haber-Bosch industrial process was to just periodical replace an expendable steel liner in the reaction vessel.
