Duplex Steel Nuts are also extensively utilized where corrosion resistance and high strength are critical. These nuts can be found in the offshore platforms, petrochemical plants, chemical processing units, and marine locations. Due to their chloride-resistant corrosion properties, they can also be found in desalination plants and undersea structures. They are further utilized in the power generation plants, paper and pulp mills, and heavy duty structural uses. Their excellent mechanical performance under high pressures and temperatures provides safe fastening in high-stress applications, which renders them the preferred choice for safety joints in industrial machinery, pipelines, and structural frameworks.
