Duplex Steel 2205 pipe fittings are made up of about 22% chromium, 5–6% nickel, and 3% molybdenum, featuring a well-balanced blend of austenitic and ferritic phases. This unique composition offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, they boast high tensile strength (around 620–850 MPa), yield strength of 450–620 MPa, and impressive toughness even at low temperatures. The dual-phase microstructure provides excellent fatigue resistance and dimensional stability, making these fittings perfect for high-pressure and high-temperature applications while ensuring long-lasting reliability in harsh chemical and marine environments.
