SS316L is used in many areas, from the food industry to nuclear power plants,
owing to its excellent corrosion resistance and mechanical strength. In this study, the effects of
phase transformations in the microstructure on hardness, surface quality, and corrosion properties
in simulated body fluid, Hank’s, and Ringer’s solutions were investigated by applying heat
treatment at different cooling media to SS316L. For this purpose, surface characterization and
electrochemical corrosion tests of heat-treated parts were carried out. The roughness of the
steel surface was increased after heat treatment. The cooling media and the corrosive environment
significantly influenced the mechanical properties and corrosion resistance. Results
illustrated that heat treatment altered the microstructure, resulting in improved mechanical
properties and corrosion resistance. The corrosion resistance of samples heat-treated in air
and oil media was better. The heat-treated sample in oil exhibited a low passive current density,
whereas the current density of those treated in water was highest in all solutions. Corrosive
environments increased weight loss and surface roughness.
