Thin Wall Stainless Steel Tube — Small Diameter & Custom Size
SHENZHEN BENXIN ELECTRONIC HARDWARE CO., LTD
Product Details
Keywords: thin wall stainless steel tube, precision steel tube, high precision steel pipe, stainless steel tubing custom size
Product Overview
Thin wall stainless steel tube — 细管 in short — is where precision really shows. Small outer diameters with thin, uniform walls are essential for instrumentation, medical devices, sensors, heat exchange and capillary applications. We produce thin wall stainless steel tube in 304 and 316L with tight OD and wall tolerances, in both seamless and welded-drawn construction, and we cut, finish and inspect every length in-house.
Key Features
- Thin wall capability — small OD with wall thickness from 0.2 mm upward, held to close tolerance
- Grades 304 / 316L — choose standard corrosion resistance or enhanced marine/chemical grade
- High precision steel pipe — tight OD tolerance and consistent wall concentricity
- Custom sizes — stainless steel tubing custom size: your OD × wall × length, no minimums on standard lines
- Clean surfaces — bright annealed, pickled or polished; suitable for high-purity use
- Cut-to-length & end finishing — precision cutting, chamfering and deburring as standard
Applications
Used in capillary tubing, hypodermic and medical instrumentation, thermocouple sheaths, sensor probes, heat exchanger coils, precision mechanical parts, fluidics and laboratory equipment.
Manufacturing & Factory Capability
Thin-wall tube demands controlled processing, and our factory is equipped for it:
- Cold drawing — multi-pass drawing achieves thin walls with uniform thickness
- Precision slitting & forming — welded-drawn tube from tightly toleranced strip
- Bright annealing — soft, clean tube with consistent metallurgy for further forming
- Surface finishing — 180#–600# polishing and electropolishing available
- Precision cutting — burr-free cut-to-length from 10 mm, tolerances verified with gauges
- Added-value machining — precision cnc components, cnc machining service and custom machining parts available for tube-based parts
- Full inspection — OD, wall, surface and length checked per batch with calibrated instruments
Customization & OEM/ODM
Specify your exact OD, wall thickness, length, material grade and finish — we produce custom sizes from drawing or sample. Coil or straight lengths, small batches and volume programs all welcome.
Quality Assurance
Wall thickness uniformity and OD tolerance are the two things we verify most strictly on thin-wall orders, using calibrated micrometers and plug gauges. Inspection reports available on request.

Frequently Asked Questions
Yes. We provide OEM/ODM custom manufacturing from your drawings in PDF, DWG, STEP, IGES or STL formats.
- What materials can you machine?
Aluminum, stainless steel (304/316), titanium alloy, copper, brass, POM, PEEK and other engineering plastics. - What is your tolerance standard?
General tolerance ±0.05mm, tight tolerance down to ±0.005mm upon request. - Can you provide material certificates & inspection reports?
Yes, 3.1 material cert, FAI, CMM inspection report are available. - What is your lead time?
Sample: 3–7 working days. Mass production: 7–15 working days, depends on complexity & quantity. - Do you support small batch & prototype orders?
Yes, we welcome prototype, low-volume and custom one-off parts. - What surface finishes can you offer?
Anodizing, sandblasting, passivation, polishing, powder coating, laser marking, deburring. - How do you handle shipping?
We support DHL, FedEx, TNT, sea freight, and can do DDP / DAP terms.
- Is there a minimum order quantity (MOQ)?
We have no strict MOQ. We accept prototype trial orders as low as 1 piece. - How can I get an accurate quotation?
Please send us your 3D STEP/IGES file, 2D drawing with tolerance, material requirement, quantity and surface finish. - Can you help with DFM optimization?
Yes. Our engineers provide free DFM suggestions to reduce machining cost and improve manufacturability. - How long is the quotation valid?
Quotation is normally valid for 30 days, subject to raw material price fluctuation.
Pricing depends on material, dimensions, tolerance, quantity and surface finish. Please send your drawings (PDF/DWG/STEP/IGES) and we will provide an exact quote, usually within 24 hours.
The price is based on material cost + machining time + surface treatment + tooling (if any) + packaging and freight.
Our standard quotes are FOB Shenzhen/Dongguan unless otherwise stated. Air or sea freight can be quoted separately according to your destination.
Our price reflects the material grade, tolerance level, full inspection and finishing quality. If needed, we can suggest cost-saving design changes (e.g. relaxing non-critical tolerances) to reduce the cost.
Yes. We provide tiered pricing — the unit price decreases as the quantity increases. Please tell us your target quantity for the best price.
