ISO 3183 PSL2 Grade L320M Material Mechanical Properties
ISO 3183 PSL2 Grade L320M has excellent corrosion resistance, making it well-suited for use in many industrial applications. The corrosion resistance of the steel can be improved by low levels of sulfur and phosphorous, as well as by adding chromium and nickel to the alloying elements. The steel's ability to resist corrosion is also dependent on the surrounding environment. In a marine environment, for example, the alloy should be treated with additional corrosion inhibitors to improve its resistance to corrosion.
