Typically, **Super Duplex Steel Pipes** are made up of about 25% chromium, 7% nickel, 3–4% molybdenum, and a touch of nitrogen, which together create a well-balanced austenitic-ferritic microstructure. This unique composition provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. The pipes boast high tensile strength (around 800–900 MPa), outstanding yield strength, and excellent impact toughness. They also feature good weldability, resistance to oxidation, and structural stability even under extreme temperatures and pressures.
