In this study, the effect of heat treatment on the microstructural and electrochemical properties of mild steel material under stress is studied. Two different heat cycles were performed in order to study the microstructural differences. For strengthening the material, austenitizing and then quenching, and to regain the ductility and toughness tempering type of heat treatment was performed. Microstructure of the FEA analysis and tensile test results. Electrochemical measurements and corrosion testing were conducted in NaCl solutions at pH 4 and 7. Heat treated samples under constant stress had lower corrosion rate than original samples at both acidic and neutral environment. The corrosion rate in acidic environment was increased by 23.5% than neutral environment for original sample, however, this change is reduced from 23.5% to 12.8% by heat treatment.
