Super Duplex Steel is a high-alloy stainless steel that usually has additions of manganese and nitrogen along with 24–26% chromium, 6–8% nickel, and 3–5% molybdenum. Excellent resistance to stress corrosion cracking and pitting caused by chloride is the outcome of this composition. High tensile strength (750–850 MPa), yield strength (550 MPa), and elongation (25%) are examples of mechanical properties. The austenitic-ferritic dual-phase microstructure offers remarkable fatigue resistance and toughness. Super Duplex Steel outperforms standard duplex and austenitic stainless steels due to these characteristics, making it perfect for use in extremely corrosive and high-stress environments.
