In this study, the four Cr-Mn-(Ni-free) austenitic steels were fabricated by vacuum induction furnace. Then plates with 10 mm thickness were fabricated by hot-rolling. Corrosion behaviour of the four Cr-Mn steels in 0.1 M H2SO4 solution was investigated using by open-circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS). The results indicated that the open-circuit potentials of the four Cr-Mn austenitic steels were found to shift towards positive direction. Also, the potentiodynamic polarization curves suggested that the four Cr-Mn austenitic steels showed comparable passive behaviour in sulfuric solutions.
