The corrosion resistance of stainless steel is primarily influenced by its alloy composition, including elements such as chromium, nickel, titanium, silicon, and aluminum. Chromium (Cr) plays a crucial role in this process due to its high chemical stability, which allows it to form a passivation film on the steel surface. This film serves to isolate the metal from external elements, thereby protecting the steel plate from oxidation and enhancing its corrosion resistance. However, if the passivation film is compromised, the corrosion resistance of the steel plate diminishes.
