A516 Gr70, A316L and Inconel 625 corrosion by LiOH-KOH mixture has been evaluated.
Tests performed in closed autoclaves under N2 atmosphere. LiOH-KOH mixture at 360 °C.
A516 Gr70 does not offer long term corrosion resistance.
Inconel 625 shows good corrosion performance but is discarded due to high cost.
A316L selected as potential candidate for the design of steam-PCM heat exchanger.
