The 329 Stainless Steel Pipe is a duplex stainless steel product, designated as UNS S32900, offering superior strength and corrosion resistance compared to standard austenitic grades. Its chromium-molybdenum composition provides exceptional resistance to chloride stress corrosion, making it suitable for aggressive environments such as chemical processing, oil and gas, and marine applications. The pipe is available in standard dimensions and forms, including coils, strips, plates, sheets, tubes, and bars.
This grade features a two-phase microstructure with roughly equal proportions of austenitic and ferritic phases, combining the benefits of both. It delivers high tensile strength, excellent weldability without weld decay, and good machinability using conventional techniques. The material’s corrosion resistance extends to halides and other harsh chemicals, which is critical for pipelines in marine or industrial settings.
Common applications for 329 stainless steel pipe include propeller shafts, pump parts, fasteners, and heat exchangers in marine environments, as well as equipment for chemical processing and oil and gas production. Buyers should specify their required dimensions, wall thickness, and surface finish, as the supplier can provide various forms to meet project specifications. Confirm adherence to international standards such as ASTM A276/A276M or ASTM A240/A240M for pressure vessel applications.

Before importing 329 stainless steel pipe, verify the supplier’s ability to meet your project’s dimensional and tolerance requirements. Request detailed mill test certificates (MTC) to confirm the material’s chemical composition, mechanical properties, and compliance with standards such as ASTM A240 or EN 10088. Additionally, check if the supplier can provide third-party inspections or certifications for critical applications.
Discuss logistics with China Economic Steel Group (Guangdong) to clarify lead times for custom sizes or large volumes. Confirm Incoterms such as FOB Foshan or CIF to your port, and agree on payment terms like TT or LC. For bulk orders, negotiate packaging options to prevent damage during transit, such as wooden crates or waterproof wrapping for overseas shipping.
Conduct quality checks upon receipt by inspecting the pipe’s surface for defects, measuring dimensions against your specifications, and testing for corrosion resistance if required. For marine or chemical applications, consider additional tests such as pitting resistance or intergranular corrosion tests to ensure long-term performance. Request documentation such as material traceability reports and compliance certificates for your records.
