Super Duplex S32760 Pipes are a high-performance stainless steel grade (UNS S32760) that belongs to the super duplex family. This alloy is engineered for maximum resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, surpassing even S32750 in some harsh environments. With high levels of chromium (~25–26%), molybdenum (~3.6–4.5%), nickel (~6–8%), and nitrogen (~0.3%), S32760 provides excellent mechanical strength and durability, making it ideal for extreme industrial conditions..
These pipes exhibit high tensile and yield strength, often around 830–850 MPa tensile and 600 MPa yield, ensuring structural reliability under high pressure. Their low thermal expansion and good fatigue resistance allow their use in temperature-fluctuating environments such as offshore oil rigs, chemical plants, and desalination systems. The alloy’s properties allow engineers to use thinner walls without sacrificing strength, optimizing both material usage and cost..
Metal Tubular Products and other global suppliers maintain substantial stocks of S32760 pipes to meet immediate project demands. They supply pipes in seamless and welded variants (ERW, EFW) and in compliance with ASTM A789 / A790 and ASME SA789 / SA790 standards. Pipes are available in a wide range of sizes, wall thicknesses, and end finishes like plain, beveled, or threaded, catering to varied engineering specifications..
Applications of S32760 are diverse, including offshore oil & gas pipelines, chemical processing, marine and seawater handling, desalination plants, and power generation systems. Its superior corrosion resistance reduces maintenance and increases service life, making it a preferred material for projects exposed to chloride-rich or highly corrosive environments.

Suppliers like Metal Tubular Products also provide quality certifications, mill test reports (MTRs), third-party inspection, and custom fabrication support to ensure compliance with international standards. Their global logistics networks ensure timely delivery to regions across Asia, Europe, the Middle East, Africa, and the Americas, supporting engineering and EPC contractors worldwide..
The fabrication and weldability of S32760 pipes make them versatile for construction and retrofitting projects. Despite its high strength, the alloy can be welded and machined effectively without losing corrosion resistance, allowing stockists to deliver bespoke solutions ranging from standard pipeline runs to complex industrial assemblies..

Super Duplex S32760 Pipes are primarily used for the transportation of oil, gas, water, and other fluids in pipeline systems. They are widely applied in onshore and offshore projects, refineries, petrochemical plants, and water transmission lines due to their excellent corrosion resistance, high strength, and good weldability.
S32760 is the UNS designation for a super duplex stainless steel grade. It has a balanced ferritic-austenitic microstructure, providing high strength and superior corrosion resistance in chloride-rich and harsh environments.
Yes, Super Duplex S32760 Pipes can be supplied in both PSL 1 and PSL 2. PSL 2 requires stricter chemical composition limits, mandatory impact testing, and enhanced quality control compared to PSL 1.
S32760 Pipes are available in Seamless (SMLS), ERW, LSAW, and SSAW forms, providing flexibility for different pressure ratings, diameters, and project requirements.
Super Duplex S32760 Pipes are stocked and supplied globally by specialized stainless steel distributors and manufacturers, offering a wide size range, quick delivery, and compliance with international standards such as ASTM A790 / ASME SA790.
