DIN 7391 Stainless Steel Tubing
DIN 7391 stainless steel tubing from ARK Steel Tube Company is a seamless precision tube manufactured through cold drawn and cold rolled processes. The tubing is available in grades 304 and 316, with outer diameters ranging from 6.0mm to 650.0mm and wall thicknesses between 1.0mm and 65mm. Lengths can reach up to 12,000mm, with tolerances held to industrial standards for hydraulic and instrumentation use. The surface finish is smooth and consistent, suitable for applications requiring minimal friction or contamination.
The material composition follows standard EN 10088-1 for austenitic stainless steels, with 304 offering good corrosion resistance in general environments and 316 providing enhanced resistance to chlorides and acidic conditions. Cold working improves mechanical strength and dimensional accuracy, making these tubes suitable for high-pressure systems. Unlike welded alternatives, seamless construction eliminates weld seams that could be failure points under cyclic stress or in aggressive media.
These tubes are commonly used in hydraulic cylinders, automotive shock absorbers, pneumatic systems, and precision machinery. Buyers include manufacturers of industrial equipment, automotive suppliers, and OEMs in Europe and North America. Packaging is typically in bundles with protective end caps, shipped in bulk via container. Trade terms are FOB China port, with minimum order quantities typically starting at 500kg, though exact volumes require direct confirmation with the supplier.

Sourcing DIN 7391 Stainless Steel Tubing from ARK Steel Tube Company - China Import Guide
Before ordering, verify the exact material grade (304 vs 316) with a chemical analysis certificate. Confirm that the outer diameter and wall thickness tolerances match your machinery requirements, as even small deviations can affect hydraulic seal performance. Request proof of seamless construction, as welded tubes may be misrepresented as seamless in some markets. Ensure the supplier provides a packing list with batch numbers and end cap protection to prevent damage during transit.
Lead time is not stated and must be confirmed directly. Typical lead times for custom sizes range from 4 to 8 weeks. Incoterms are likely FOB Shanghai or Ningbo, but confirm port of loading and responsibility for export clearance. Payment terms are not listed; common practices include 30% advance with balance against copy of bill of lading. Avoid full prepayment without third-party inspection or escrow services.
Perform a visual inspection for surface defects such as scratches, pits, or oxidation. Use a micrometer to verify wall thickness at multiple points. Request a pressure test report if the tubes will be used in high-pressure systems. For critical applications, arrange for third-party inspection by SGS or Bureau Veritas before shipment. Ensure all documentation includes material test reports, packing list, and commercial invoice with correct HS code for customs clearance.
