Steel Industry Glossary › Duplex SteelWhat are the main properties and standards for duplex steel in industrial applications? Duplex steel combines high strength and corrosion resistance, making it ideal for harsh environments. It typically has a minimum yield strength of 450 MPa and better pitting resistance than austenitic stainless steels. Key standards include ASTM A240 for stainless steel sheets and ASME SA249 for welded tubes, ensuring 0% claim rate on 2024-2025 nuclear-spec shipments and performance in chemical and oil industries.
Duplex Steel A family of stainless steels with a mixed microstructure of approximately equal proportions of austenite and ferrite, offering superior strength and corrosion resistance.
