The high corrosion resistance of 430S15 steel grade is attributed to its high chromium content, which forms a protective oxide layer on the surface of the steel, preventing corrosion. The low carbon content also helps to improve its resistance to intergranular corrosion. These properties make 430S15 steel grade suitable for applications in environments with high corrosion potential, such as marine and chemical processing industries.
