Do not equate the intermediate heat treatment defined in 131.6.1 of ASME B31.1 as being intermediate stress relief.

but is there any advantage or disadvantage for using them?

Dehydrogenation treatments are used when welding hardenable materials to mitigate hydrogen induced cracking, especially useful for welding P91 piping and other Cr-Mo-V martensitic alloy components prior to final PWHT. Dehydrogenation treatments are also used after plating operations on hardened materials to prevent hydrogen cracking after plating.
