316L Stainless Steel Pipe for Automotive
Ark Steel Tube supplies 316L stainless steel seamless pipe from Taizhou, Zhejiang, China, engineered for automotive exhaust systems, fluid transport, and structural applications. The material conforms to UNS S31603 within the 300 Series, with an outer diameter range of 3.2 mm to 25.4 mm and wall thickness from 0.2 mm to 2.5 mm. Length is available to customer requirement. The pipe meets AISI, ASTM, DIN, EN, and JIS standards, with ISO certification stated by the supplier.
316L is an austenitic stainless steel with deliberate low carbon content (below 0.03 percent) to mitigate sensitisation and intergranular corrosion after welding, a critical property for automotive exhaust components that experience thermal cycling. The seamless construction produced by Ark Steel Tube eliminates the weld seam, offering uniform circumferential strength and reduced leak path risk compared to welded alternatives. Typical automotive grades in this category require resistance to oxidation up to approximately 870 degrees Celsius in intermittent service, with creep resistance becoming a factor at sustained elevated temperatures.
Buyers span automotive OEMs, tier-one exhaust system fabricators, and aftermarket parts distributors. The round pipe geometry suits mandrel bending and hydroforming operations common in exhaust manifold and downpipe manufacture. Trade terms offered include FOB, CIF, and CFR, with payment by T/T. The supplier targets global markets and does not disclose minimum order quantities or lead times in the listing, so buyers should confirm these directly with Ark Steel Tube before committing to production schedules.
| Material Grade | 316L (UNS S31603), 300 Series austenitic stainless steel |
| Outer Diameter (OD) | 3.2 mm to 25.4 mm |
| Wall Thickness | 0.2 mm to 2.5 mm |
| Length | Per customer requirement (standard cut lengths typical for automotive tubing: 4 m to 6 m, confirm with supplier) |
| Manufacturing Process | Seamless (cold-drawn or hot-finished, typical for 316L automotive pipe) |
| Applicable Standards | AISI, ASTM, DIN, EN, JIS (ASTM A213/A269 typical for seamless instrumentation and heat exchanger tubing; ASTM A312 typical for general service) |
| Corrosion Resistance | Excellent resistance to pitting and crevice corrosion in chloride environments, typical molybdenum content 2.0-3.0% in 316L |
| Maximum Service Temperature (Oxidation) | Up to approximately 870 degrees Celsius intermittent, 925 degrees Celsius continuous (typical for 316L in oxidising atmospheres) |
| Carbon Content | Maximum 0.03% (defining characteristic of L-grade, reducing carbide precipitation during welding) |
| Payment Terms | T/T (Telegraphic Transfer) |
Ark Steel Tube is based at E802, Xintai Square, Taizhou, Zhejiang, China, postal code 318000. The supplier's trust tier is classified as "harbor" within the marketplace system, with a response rate of 0.00 percent and an average response time of zero hours recorded. These metrics suggest the supplier has not engaged with buyer enquiries through the platform's messaging system, or that response data has not yet accumulated.
The listing presents the company as a source of 316L stainless steel pipe under the brand name KWKSTEEL, with model numbers referencing ASTM/ASME specifications. No information is provided about year of establishment, production capacity, factory floor space, number of employees, annual revenue, or named clients. The supplier does not list specific certifications beyond ISO, nor does it detail quality control procedures, inspection equipment, or export experience. Buyers should verify factory registration, ISO scope, and any automotive industry approvals (such as IATF 16949) directly with Ark Steel Tube before qualifying them as a supply chain partner.
316L stainless steel seamless pipe is a premium-grade tubing solution widely used in automotive exhaust systems, fluid transport, and structural applications. Manufactured to ASTM/ASME standards with excellent corrosion and oxidation resistance, this pipe offers superior durability in high-temperature environments. Ideal for B2B buyers seeking reliable industrial piping with ISO-certified quality from Zhejiang, China, available in standard dimensions for seamless integration into manufacturing operations.

Sourcing 316L Stainless Steel Pipe for Automotive from Ark Steel Tube - China Import Guide
Before placing an order with Ark Steel Tube, verify the supplier's ISO 9001 certificate scope covers seamless stainless steel pipe manufacture, not merely trading activity. Request a recent mill test certificate from production matching your required dimensions, checking that chemical composition and mechanical properties conform to ASTM A312 or your specified standard. Confirm whether the supplier holds any automotive industry-specific quality certifications, as the listing does not indicate IATF 16949 or equivalent. Ask for reference customers in the automotive exhaust sector, and consider an initial sample order to evaluate dimensional accuracy and surface quality before committing to volume procurement.
Logistics from Taizhou, Zhejiang typically ship through Ningbo-Zhoushan Port or Shanghai Port, with transit times to European destinations of 25-35 days and to North American west coast of 14-18 days under normal scheduling. The listing offers FOB, CIF, and CFR terms. FOB Ningbo or Shanghai is preferable if you maintain freight forwarding relationships; CIF shifts ocean risk to the seller but may include less flexible carrier choices. Payment is specified as T/T, which usually involves 30% deposit with balance against copy of bill of lading, though Ark Steel Tube may propose alternatives. Lead times are not stated and must be confirmed, including whether raw material is held in stock or mill-ordered against your purchase order. Ask about production scheduling during Chinese New Year when Zhejiang factories typically close for 2-3 weeks.
Quality assurance for 316L automotive pipe should include incoming inspection of dimensions using calibrated ring gauges and wall thickness ultrasonic gauges, comparing against mill certificates. Perform spot checks for surface defects, scale,Initialize chemistry verification through third-party laboratory analysis if mill certificates are from non-accredited bodies. For critical exhaust applications, require mechanical testing including tensile strength (minimum 485 MPa typical for annealed 316L), 0.2% proof stress (minimum 170 MPa), and elongation (minimum 35%). Documentation should include material certificates to EN 10204 3.1 or 3.2, depending on your quality plan requirements. Consider pre-shipment inspection by an independent agency such as SGS or Bureau Veritas for first orders, particularly given the supplier's zero recorded response rate on the platform, which may indicate communication challenges that could affect order execution and dispute resolution.
