Abstract This paper mainly investigated the corrosion of Fe-based 316SS and seven Ni-based alloys in molten NaCl-KCl-MgCl2 under N2 at 700 °C using static immersion experiment and microstructure observation. All alloys suffered the selective dissolution of Cr, resulting in the formation of subsurface voids. 316SS exhibited worse corrosion resistance than that of Ni-based alloys. Among Ni-based alloy, the corrosion resistance of alloys increased in the following order of Ni-Fe-Cr
