The 4 torx screws that rust out and get stuck are steel, but it may be possible there is a local dissimilar metals chemistry cocktail that occurs in the square part of those coolant pipe assemblies if you don't drive the car very often.

I had to drill the head off of a couple of mine when I took them off, but luckily the thread itself wasn't too seized and vice grips took care of things.
