ASTM ASME U3 Super Steel Pipes & Tubes

Product Description
ASTM ASME U3 Super Steel Pipes & Tubes are high-performance duplex alloys designed for exceptional strength and corrosion resistance in challenging industrial environments. Composed of a balanced ferrite-austenite microstructure (typically 23% chromium, 4.5% nickel, 2.5% molybdenum, and 0.15% nitrogen), these pipes/tubes offer superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich media, seawater, and acidic solutions. Engineered to ASTM A790 and ASME SA790 standards, they combine high tensile strength (up to 800 MPa) with excellent impact toughness, making them ideal for offshore oil & gas, chemical processing, desalination plants, and marine engineering. Their duplex structure ensures low thermal expansion and high fatigue resistance, while compliance with strict industry standards guarantees reliability in high-pressure, high-corrosion applications. Available in seamless or welded configurations, these pipes/tubes deliver long-lasting performance in environments where traditional stainless steels fall short.
