321 seamless stainless steel pipe
This 321 seamless stainless steel pipe is manufactured from titanium-stabilized austenitic stainless steel, grade 321 (18Cr-12Ni-Ti), designed to resist intergranular corrosion at elevated temperatures. The product meets ASTM and ASME standards, with outer diameters ranging from 2 mm to 630 mm, wall thicknesses from 1 mm to 40 mm, and standard lengths of 6 meters, though custom lengths are available on request. Its titanium stabilization ensures stability in high-temperature environments up to 900°C, making it a reliable choice for critical applications.
The material composition includes chromium and nickel with titanium additions, which prevent chromium carbide precipitation during welding or high-temperature exposure. This grade is typically supplied in hot-rolled or cold-rolled finishes, with surface treatments tailored to the application. Standard packaging includes kraft paper wraps, steel strip bundling, and wooden matting, with seaworthy wooden cases available for export. The pipe is commonly used in petroleum refining, chemical processing, power generation, and aerospace exhaust systems due to its durability and corrosion resistance.
This product is ideal for importers sourcing high-temperature resistant piping for industrial applications. It is traded globally with flexible packaging options for containerized export. Common industries include petroleum, chemical, construction, and shipbuilding, where resistance to oxidation and corrosion is critical. Buyers should confirm specific dimensional tolerances and surface finish requirements, as these can vary based on the production method and intended use.

Sourcing 321 seamless stainless steel pipe from Zhejiang Yingsheng Stainless Steel Pipe Co., Ltd. - China Import Guide
Before ordering, verify the pipe’s dimensional tolerances and surface finish to ensure compatibility with your application. Confirm that the material grade (321) meets the specific standards required for your industry, particularly for high-temperature or corrosive environments. Request mill test certificates to validate the chemical composition and mechanical properties.
Discuss logistics details with the supplier, including lead times, which typically range from 10 to 25 days depending on quantity. Clarify Incoterms (e.g., FOB, CFR) and payment terms (e.g., L/C, T/T) to avoid misunderstandings. Containerized export is standard, but confirm packaging options for seaworthy protection during transit.
Inspect the pipe upon delivery for surface defects, dimensional accuracy, and packaging integrity. For critical applications, arrange third-party inspections or request additional testing, such as hydrostatic or non-destructive testing. Ensure all documentation, including material certificates and compliance with ASTM/ASME standards, is provided before finalizing the order.
