ASTM ASME DS-2 Super Steel Pipes & Tubes

ASTM ASME DS-2 Super Steel Pipes & Tubes are high-performance duplex alloys engineered for superior strength and corrosion resistance in challenging industrial applications. Composed of a balanced ferrite-austenite microstructure (typically 25% chromium, 7% nickel, 3.5% molybdenum, and 0.3% nitrogen), these pipes/tubes offer exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-laden environments, seawater, and acidic process streams. Meeting ASTM A790 and ASME SA790 standards, they combine high tensile strength (up to 900 MPa) with excellent impact toughness, making them ideal for offshore oil & gas platforms, chemical processing plants, desalination systems, and high-pressure pipelines. Their duplex structure ensures low thermal expansion and high fatigue resistance, while strict quality certifications guarantee reliability in harsh, high-corrosion conditions. Available in seamless or welded configurations, DS-2 super steel pipes/tubes deliver long-lasting performance where traditional materials struggle with durability and integrity.
