UNS N08330 Alloy ASME SB-535 Seamless Tubing
The UNS N08330 alloy ASME SB-535 seamless tubing is an austenitic nickel‑chromium‑iron steel designed for extreme heat. It contains approximately 35 % nickel, 19 % chromium, with the balance iron and silicon, matching the UNS N08330 composition. Certified to ASME SB‑535, the tube tolerates continuous service temperatures up to 2100 °F (1150 °C). Shangdun Special Materials Co.Ltd. manufactures the tubing in standard schedules and can produce custom outer diameters on request.
The alloy’s austenitic structure gives it superior oxidation and thermal‑fatigue resistance compared with standard stainless steels. Typical industry dimensions for this grade range from 0.5 in to 6 in outside diameter with wall thicknesses between 0.035 in and 0.5 in, tolerances of ±0.001 in are common. It is supplied in bundled packs or wooden crates, each tube marked with heat‑number and material grade. The material is often selected for furnace components, heat‑treating equipment and high‑temperature chemical processing where corrosion resistance is critical.
Importers in power generation, petrochemical and aerospace sectors frequently source this tubing for its reliable performance in corrosive, high‑temperature environments. Shangdun offers export‑grade packaging and can arrange shipment under various Incoterms, but exact minimum order quantities and lead times are not listed and should be confirmed directly. Buyers are advised to request mill test certificates and verify compliance with ASME SB‑535 before finalising purchase.

Sourcing UNS N08330 Alloy ASME SB-535 Seamless Tubing from Shangdun Special Materials Co.Ltd. - China Import Guide
Before placing an order, importers should verify that the supplied tubing matches the UNS N08330 composition and ASME SB‑535 certification. Request the latest Mill Test Certificate and, if possible, a recent chemical analysis report to confirm the nickel and chromium percentages. Check that the supplier’s corporate registration and the harbor trust tier are up‑to‑date, and confirm the exact dimensions and tolerances required for your application. Establish clear communication channels to address any deviations before production.
Shipping terms are negotiated directly with Shangdun Special Materials, and buyers should clarify the preferred Incoterm - common choices include FOB Jiaxing port or CIF Shanghai for sea freight. Although the listing does not state a fixed lead time, typical production cycles for custom dimensions range from a few weeks to several months, so confirm the schedule early. Discuss container loading plans, whether the tubing will be palletised or crated, to avoid damage during transit.
Quality assurance can be reinforced by arranging a third‑party inspection at the factory or upon arrival at the destination port. Request visual inspection reports, dimensional checks, and non‑destructive testing results in addition to the MTC. Ensure that the final documentation package includes the certificate of conformity, test reports and packing list, which will facilitate customs clearance and guarantee that the material meets the specified performance criteria.
