Whether a stainless steel is corrosion resistant in a specific environment depends on a combination of its chemical composition and the aggressiveness of the environment.How corrosion occurs The corrosion resistance of stainless steel is attributed to the thin passive film that forms spontaneously on its surface in oxidizing environments if Corrosion resistance of duplex stainless steelsThe prevention of corrosion is assumed to be suitable if the attack rate is lower than 0.1 mm per year.Duplex steel grades contain large magnitude of chromium that enables them to offer good corrosion resistance in the different environments.Sulfuric acid.Following diagram shows the corrosion resistance in sulfuric acid.
