Their Super Duplex Steel Tubing S32750 is crafted to deliver long-lasting, efficient, and safe solutions for challenging industrial operations.
Super Duplex Steel Tubing S32750 is a top-notch alloy that mainly consists of 24–26% chromium, 6–8% nickel, and 3–5% molybdenum, along with a few trace elements like nitrogen and manganese. This special blend gives it fantastic resistance to pitting, crevice, and stress corrosion cracking. On the mechanical side, the tubing boasts a tensile strength of around 830–1000 MPa, a yield strength of 550–700 MPa, and an elongation of 25–30%, which means it combines impressive toughness with high strength. Its unique dual-phase microstructure, made up of austenite and ferrite, ensures it can withstand extreme temperatures and harsh chemical environments.
