Duplex Steel ERW Pipes feature a well-balanced microstructure of austenite and ferrite, typically comprising 22–25% chromium, 4–7% nickel, 3% molybdenum, and nitrogen to enhance strength. This unique composition ensures outstanding resistance to stress corrosion, pitting, and crevice corrosion. These pipes boast impressive mechanical strength, with a typical yield strength of around 450 MPa and tensile strength reaching up to 620 MPa. Their elongation falls between 25–30%, and they perform admirably in both low and high-temperature settings, making them perfect for high-pressure and corrosive applications.
