With superior tensile and yield strength, Super Duplex S32750 is two times as strong as conventional austenitic stainless steels. With such characteristics, wall thickness and weight can be reduced, providing cost-saving solutions for high-pressure applications without a loss in performance or safety. The material's superior PREN (the formula for which is typically above 40) guarantees excellent resistance to localized corrosion, which is perfect for pipelines, pressure vessels, and heat exchangers used in aggressive corrosive conditions.
