The corrosive effects of 60 % NaNO 3 /40 % NaNO 3 have been tested at 390 and 550 °C, in order to simulate the working conditions in two principal concentrated solar power (CSP) plants, on stainless steel (AISI 304, 430) and on a low-Cr alloy steel (T22) containing 2.25 % Cr. The corrosion rates wer...
