Stainless steels are widely used in industry with their corrosion resistance and high formability. Since ferritic stainless steels do not contain nickel, they rise to a more advantageous position in terms of price compared to austenitic stainless steels. Stainless steel sheets are cast as slabs for hot rolling after the chemical composition and necessary refining processes are completed. Stainless steels, which become flat plates with hot rolling, are subjected to cold rolling processes after heat treatment and surface treatment and are reduced to the thickness desired by the user. After cold rolling, annealing is applied to relieve the stress in the structure. During annealing, the high temperature oxides formed on the surface of the material must be removed from the surface. For this, descaling and pickling operations are applied with acits. In this study, the effects of oxides, descaling acids and their combinations on the material surface under different annealing conditions were investigated. At the same time, the morphology of the surface oxides, the oxide structure and the presence of spinel oxides are effective on the ability of acids to dissolve oxides. Considering the reaction kinetics in the study, the decrease in the density of the complex oxysts formed in the oxide structure accelerated the dissolution kinetics. For this reason, it was observed that a better dissolution was obtained on the samples annealed at 750 degrees and 850 degrees for 65 seconds, especially in the sulfuric acid solution compared to the nitric acid solution.
