Relevant for Saturated Water -
Chapter 11 Preboiler And Boiler Corrosion Control
from Andrew Smart:
You don't need stainless steel, just some steel appropriate for boilers. You'd want to do magnetite passivation (black oxide) to prevent corrosion on the inside as is done with boilers. If appropriate water is used (slightly basic pH and no oxygen) then corrosion of the magnetite layer won't occur, but otherwise you'd want a maintenance procedure to restore/maximize the thickness of the magnetite layer (essentially add chemicals and heat into the loop every year or so). I have ideas here but hadn't done anything myself yet.
