As an improved alloy material, super13Cr has significantly improved mechanical properties and corrosion resistance compared to 13Cr. This material improves welding performance by reducing carbon content while maintaining the microstructure of martensite, making it more adaptable and reliable in industrial applications.
Super13Cr is mainly used in key components such as OCTG pipelines, shells, and downhole equipment for well completion. This material has good corrosion resistance and can maintain a stable working state in harsh environments.
