TP439/TP410 Stainless Seamless Steel Tube
The TP439/TP410 stainless seamless steel tube is a ferritic‑martensitic product from the 400 series, supplied by ARK Steel Tube Company in China. It is manufactured from stainless steel 400 series TP439/TP410 alloy, offering a balance of corrosion resistance and high‑temperature strength. The tube dimensions cover outer diameters from 6 mm to 273 mm with wall thicknesses ranging between 0.5 mm and 25 mm. All sizes are produced to meet ASTM A268 / ASME SA268 specifications for general service.
These grades exhibit good weldability, magnetic properties and superior creep resistance compared with austenitic grades, making them cost‑effective for demanding environments. Typical industry practice tolerates an outer‑diameter deviation of ±0.2 mm and wall‑thickness deviation of ±0.1 mm for this size range. Standard surface finish is mill finish, and tubes are commonly supplied in 6 m lengths, bundled in packs of ten. The material density is approximately 7.8 g cm‑3, a typical value for 400‑series stainless steel.
Applications include heat‑exchanger headers, automotive exhaust systems, industrial piping and petro‑chemical plant components, where moderate corrosion resistance and strength are required. Procurement is usually undertaken by OEMs, engineering firms and bulk distributors that source in metric tonnes. As the listing does not disclose MOQ, lead time or Incoterms, buyers should confirm these details directly with ARK Steel Tube Company before placing an order.

Sourcing TP439/TP410 Stainless Seamless Steel Tube from ARK Steel Tube Company - China Import Guide
Before placing an order, importers should request the mill test certificate confirming the TP439/TP410 chemical composition and mechanical properties, as well as a dimensional inspection report for the selected OD and wall thickness. Verify that the supplier can provide compliance documentation for ASTM A268/ASME SA268. Confirm the exact packaging configuration and whether the tubes will be bundled or palletised as described. It is also prudent to check the company’s harbour‑tier verification status and recent trade references.
Logistics arrangements should be clarified, including the preferred Incoterm such as CIF, FOB or EXW, and the expected lead time for the ordered sizes. Because the listing does not state a specific delivery schedule, the buyer must obtain a confirmed shipment timeline from ARK Steel Tube Company. Payment terms are typically negotiated on a T/T basis, but alternative methods can be discussed during contract finalisation. Any freight forwarder requirements, such as container type or weight limits, should be communicated early.
Upon arrival, the consignee should arrange a dimensional verification using calibrated gauges to ensure adherence to the ±0.2 mm OD and ±0.1 mm WT tolerances. A visual inspection for surface defects and a magnetic test can confirm the ferritic‑martensitic nature of the material. Request the original mill test report and a certificate of conformity to accompany the cargo. Retaining these documents facilitates customs clearance and future quality audits.
