Super Duplex Steel Instrumentation Tubing is typically made up of around 25% chromium, 7% nickel, and 4% molybdenum, with added nitrogen to boost corrosion resistance and mechanical strength. Its unique dual-phase microstructure, which combines ferrite and austenite, provides a tensile strength of about 750 MPa and a yield strength close to 550 MPa. These tubes are designed to resist pitting, crevice corrosion, and stress corrosion cracking, making them ideal for high-pressure, corrosive environments. With a smooth finish and precise tolerances, they ensure reliable performance in sensitive instrumentation and control applications.
