Just a simple observation...My mag 9.5 has been running for 2 years
no rust. I'll leave the engineering materials conversation alone.
I do enough of this during the day.

They used to use the ss in pond mag pumps, and the dark ones in the
aquarium mag pumps, but now you never know which ones they will use.

Mag drive uses two types of screws, stainless steal, and a dark colored
screw. The dark colored screw holds up better than the ss screw. It seems
odd the way they sometimes use one over the other.
