What material wouldn't degrade over the lifetime of the chimney?

  Steel... just like via ferrata. These chimneys aren't more than like 150 years old max.

    Maybe. I don't know. I've seen plenty of old fixed ladders that have rusted to uselessness, but they weren't 150 years old.

    Via ferratas are almost always embedded into pure rock, generally limestone, right? Brick and mortar is quite a bit different.
