Abstract:
Additively manufactured AISI 316 L stainless steel samples were heat treated at temperatures from 400 °C to 1100 °C, and the corrosion behavior in chloride environments was electrochemically studied. Heat treatments at 400 °C and 650 °C increased the grain size and the treatment at 1100 °C formed MnCr2O4 inclusions. Also, these postprocessing techniques reduce the hardness and increased the porosity. Heat treatment at 400 °C increased the polarization resistance and maintained the pitting corrosion mechanisms of the additively manufactured samples. Heat treatments at higher temperatures reduced the polarization resistance but changed the corrosion resistance mechanisms.
