At Nascent Pipe & Tubes, we are a leading supplier and stockist of high-quality Duplex Steel S32205 Tubes, known for their exceptional strength, excellent corrosion resistance, and superior performance under extreme conditions. These tubes are manufactured as per international standards, including ASTM A789, and are identified by their universal standard number UNS S32205. Designed for critical applications, our duplex tubes deliver high yield strength, excellent weldability, and resistance to stress corrosion cracking, making them suitable for industries like oil & gas, marine, petrochemical, and power generation.
The UNS S32205 Tubes are composed of a dual-phase microstructure that contains a balanced mixture of austenitic and ferritic stainless steel, providing them with enhanced mechanical properties compared to traditional stainless steels. These ASTM A789 Duplex Steel Tubes perform reliably in chloride-rich environments, exhibiting outstanding resistance to pitting, crevice corrosion, and erosion. Our tubes are offered in both seamless and welded formats, available in various sizes, schedules, and thicknesses to meet project-specific requirements.
