The corrosion resistance generated by molten salts at high temperature in nickel-iron-chromium alloys was studied. Alloys with different concentrations of carbon and aluminum plus titanium were produced and the chemical composition of the samples was determined by optical emission spectrometry. Samples were cold rolled with a cross and unidirectional rolling deformation of 15%, after that a heat treatment was performed to get the desired microstructure. SEM and optical microscopy were used to analyze the microstructure and determining the grain size. EDS analysis was used for determining the chemistry of inter- and intra-granular precipitates. Finally, a high temperature corrosion process was carried out using vanadium pentoxide molten salts. SEM was used to analyze the type of corrosion. A high resistance to hot corrosion was found for this alloy system and a direct relationship between carbon concentration and corrosion rate. No significant influence of the concentration of aluminum and titanium on the corrosion rate was observed.
