Duplex Stainless Steel Pipes (ASTM A358, A789, A790)
(2 Product Views)
Product description
Duplex stainless steel pipes combine the high strength of martensitic stainless steels with the superior corrosion resistance of austenitic grades. This unique microstructure makes them ideal for applications where standard 316L stainless steel may fail due to chloride pitting or stress corrosion cracking. These pipes are manufactured to meet strict international standards, including ASTM A358, A789/ASME SA 789, and ASTM A790/ASME SA 790, ensuring reliability for critical infrastructure projects.
Available in a range of high-performance grades such as UNS S31803, S32750, S32760, S32205, F51, and S32550, these pipes offer versatile solutions for demanding industries. The material's high yield strength allows for thinner wall sections compared to conventional stainless steels, resulting in lighter weight and easier handling without compromising on durability.
Key Features & Applications
- Exceptional resistance to chloride-induced stress corrosion cracking and pitting.
- Higher yield strength (approx. 50% higher than standard austenitic grades) for reduced wall thickness.
- Compliant with ASTM A358, A789, and A790 standards for seamless and welded configurations.
- Wide selection of grades including S31803, S32750, and S32205 for specific chemical environments.
- Ideal for oil & gas, desalination, chemical processing, and offshore platforms.
