S32760 Super Duplex Stainless Steel Pipe is a high-strength, corrosion-resistant pipe specifically designed for demanding environments such as seawater, chemical processing, and offshore engineering. With a balanced microstructure of austenite and ferrite, this material offers outstanding resistance to pitting, crevice corrosion, and chloride-induced stress cracking.
Our S32760 Super Duplex Stainless Steel Tube is manufactured in compliance with ASTM A790 / ASME SA790 / EN 10216-5 standards and supplied with mill test certificates, EN 10204 3.1/3.2 documentation, and optional third-party inspections (SGS, BV, TÜV). Backed by reliable quality control, stable mechanical properties, and proven performance, this pipe is a preferred choice for critical industrial applications.
Key Features & Advantages
Superior Corrosion Resistance: Excellent durability in aggressive chloride environments, outperforming 316L and 904L stainless steels.
High Mechanical Strength: Yield strength nearly double that of standard austenitic stainless steels.
Excellent Fatigue & Impact Resistance: Suitable for dynamic and high-pressure systems.
Reliable Weldability: Maintains mechanical integrity after welding and fabrication.
Global Standards Compliance: Produced under ASTM, ASME, EN, and ISO certifications with full traceability.
Applications
The S32760 Super Duplex Stainless Steel Pipe is widely adopted in industries requiring strength and long-term corrosion resistance:
Offshore platforms, subsea pipelines, and risers
Oil & gas refineries and chemical processing plants
Desalination facilities and water treatment systems
Pressure vessels, boilers, and heat exchangers
Marine construction and shipbuilding
Pulp & paper industry equipment
