Duplex Steel Boiler Tubing features a well-balanced microstructure of austenite and ferrite phases, with a chemical makeup of around 22–25% chromium, 4–7% nickel, 3–5% molybdenum, along with small amounts of nitrogen and manganese. This unique blend provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, Duplex steel boasts high tensile strength (620–850 MPa), yield strength (450–550 MPa), and good elongation (25–35%). With a density of about 7.8 g/cm³, Duplex steel maintains its strength even at elevated temperatures, making it perfect for critical boiler applications under tough operating conditions.
