Investigation on Corrosion Behaviors of Ternary Nitrate Molten Salt on 304 and 316L at High Temperatures
Source abstract
Abstract
The corrosion behaviors of molten salt (67.2 wt.%KNO3-13.5wt.%LiNO3-19.3wt.%Ca(NO3)2) to stainless steels 304 and 316L are unclear. In this study, both the static and electrochemical tests were carried out at 300 and 500 °C. After the static corrosion tests for 1440 h, the static corrosion rates of 304 and 316L were about 0.031 and 0.014 mm/a at 500 °C. The predicted electrochemical corrosion rates were about 0.027 mm/a for 304 sample and 0.015 mm/a for 316L sample at 500 °C. Furthermore, the temperature has a key effect on the corrosion behavior based on XRD, SEM and EDS testing results.
