Super Duplex Steel Seamless Pipes are mainly made from austenitic-ferritic stainless steel, typically in the UNS S32750 or S32760 grades, which contain around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen. These components work together to provide remarkable corrosion resistance and impressive mechanical strength. The pipes boast a tensile strength of about 800 MPa, a yield strength of 550 MPa, and an elongation of roughly 25%. Their unique dual-phase structure significantly enhances their resistance to stress corrosion cracking and pitting, making them perfect for harsh environments and demanding mechanical applications.
