I would think all tanks corrode. Even with a water relief (given the water comes out brown...).
Hydrostatic testing is one thing but not so practical. Putting some rust prohibitor (like undercoating) I always wondered about.
I don’t know about compressor tanks but years ago for awhile they were putting an epoxy coating on the inside of steel scuba tanks. They were finding pinholes in the coating and rusting underneath.
