SA588GrK Weathering Alloy Steel Plate
Atmospheric Corrosion Resisting Plate Products Description
SA588Gr.K weathering steel sheet is a highly weather-resistant structural steel that complies with the American ASTM A588/A588M standard. This steel is designed for structural parts that can maintain good performance in extreme climate environments without the need for additional coating protection.
SA588Gr.K corten structural steel has excellent resistance to atmospheric corrosion, especially in areas where there are corrosion-accelerating factors such as moisture and salt spray.
SA588Gr.K plate corten steel contains specific alloying elements such as copper, chromium, and nickel, which enable a dense protective oxide film to form on the steel surface to prevent further corrosion.
