[MW:743] Re: how to find hydrogen concentration

Theer is no such method and also it is not the criteria to select the appropriate steel.
We need to see hydrogen % in the process fluid being handled in the vessel and if it is above certain level, the steel shall be vacuum degassed one and  also  API 941 gives guidelines for steel selection.
