Seamless Stainless Steel ASTM A312 TP304 Tube
ARK Steel Tube Company supplies seamless stainless steel tubes manufactured to ASTM A312 using TP304 grade austenitic stainless steel. The tubes are available with outer diameters from 3 mm up to 813 mm and wall thicknesses ranging from 0.05 mm to 120 mm. Chemical composition complies with 18‑20 % chromium, 8‑10.5 % nickel and a maximum carbon content of 0.08 %. The product meets the ASTM A312 standard and is listed under the company’s stainless‑steel catalogue.
TP304 is a typical austenitic grade offering corrosion resistance in acidic and chloride environments, with typical tensile strength between 520 MPa and 620 MPa. Standard surface finish is 2B, and the tubes can be supplied with a 2B or polished finish on request. Dimensional tolerances are generally ±0.5 mm on diameter and ±0.05 mm on wall thickness, which aligns with common industry practice for large‑diameter stainless sections. Packaging is usually in bundled coils or straight lengths, with optional passivation for enhanced corrosion protection.
These tubes are suited for oil and gas pipelines, petrochemical process equipment, food‑processing lines and architectural applications. The supplier mentions flexible minimum order quantities and global export capability, but exact MOQ and lead‑time are not disclosed in the listing and should be verified directly. Payment methods and incoterms are negotiable, and buyers are advised to request test certificates such as ASTM A312 compliance and mill test reports before finalising a purchase.

Sourcing Seamless Stainless Steel ASTM A312 TP304 Tube from ARK Steel Tube Company - China Import Guide
When sourcing these stainless tubes, first confirm the exact outer diameter, wall thickness and the chemical composition that matches TP304.

Verify whether the supplier can provide the desired surface finish and whether passivation is required for your application.
Logistics for ARK Steel Tube Company usually involve sea freight from the ports of Ningbo or Shanghai. While the listing does not give a specific lead time, buyers should ask for an estimated production schedule and discuss incoterms such as FOB, CIF or DDP.
