Özet

The corrosion behaviors of G-X CrNiMoNb 18-10 austenitic stainless steel in (0.1, 1, 2 and 3 M) HCl, H2SO4, and H2SO4 + HCl (1:1) acidic solutions was investigated by the potentiodynamic polarization method and the weight loss method. Furthermore, the corrosion strength of austenitic stainless steel that exposed to acidic solutions for a specific duration of time was determined by hardness measurements. The chrome and other elements (Ni, Mo, etc.) contents of G-X CrNiMoNb 18-10 austenitic stainless steels that exposed for long durations of time in acidic solutions were measured by elemental analysis, while their respective surfaces were analyzed using photographs.
