    This study aimed to investigate the corrosion behaviour of annealed stainless steel mesh. Thermal oxidation treatments were applied to steel mesh in a muffle furnace at 500 °C, 700 °C and 900 °C. Surface morphology of annealed and non-annealed stainless steel meshes was compared before and after polarization. The roughness of the steel surface was increased after heat-treatment. The corrosion properties of non-annealed and annealed steel were determined using linear sweep voltammetry. The corrosion behaviour of annealed stainless steel was examined utilizing a potentiostat in a 3.5 wt.% NaCl, 1 M H2SO4 and 1 M KOH electrolytes. The corrosion susceptibility of heat-treated stainless steel was more than that of non-heat treated stainless steel in alkaline electrolyte. While pitting corrosion of non-annealed and annealed stainless steel was different, corrosion potential and current of steel mesh without heat treatment were the same as the steel meshes annealed at 500 °C and 700 °C. Corrosion current and corrosion potential of non-annealed steel were the same as 500 °C annealed steel mesh in acidic medium.
