304 Stainless Steel Pipe & Tube — Factory-Direct Supplier
SHENZHEN BENXIN ELECTRONIC HARDWARE CO., LTD
Product Details
Keywords: stainless steel pipe, stainless steel pipe 304, stainless steel tube, metric steel tube
Product Overview
304 is the workhorse grade of stainless steel pipe: excellent corrosion resistance, good formability and stable mechanical properties at a competitive price. We supply stainless steel pipe 304 in both welded and seamless construction, in metric and inch dimensions, with precise wall thickness and clean, burr-free ends. Whether you need a few meters for prototyping or truckload quantities for a long-term program, every pipe leaves our factory inspected and traceable.
Key Features
- Grade 304 / 304L — balanced corrosion resistance for general industrial, food and architectural use
- Welded or seamless — both constructions available to match application and budget
- Metric steel tube sizes — wide range of OD × wall thickness combinations, from small diameters up to large bore
- Precise dimensions — OD and wall thickness held to standard tolerances, verified with calibrated gauges
- Clean finishes — pickled, bright annealed or polished surfaces; cut ends deburred
- Custom lengths — cut-to-length service from 10 mm to 6 m and longer
Applications
Used for fluid and gas transport, structural framing, handrails, heat exchangers, food-processing equipment, furniture and general engineering across plumbing, HVAC, machinery and construction projects.
Manufacturing & Factory Capability
Our stainless steel tube production covers the complete process chain:
- Slitting & forming — precise strip slitting and roll forming for welded tube
- TIG / high-frequency welding — stable weld seams with full weld penetration control
- Cold drawing — seamless and welded tube drawn to tight OD/wall tolerances
- Annealing & pickling — bright annealing and pickling/passivation restore corrosion resistance
- Surface finishing — 180#–600# polishing, matt and mirror finishes available
- Cutting & end finishing — cut-to-length, chamfering and deburring in-house
- Testing — eddy current and hydrostatic testing options for pressure applications
Customization & OEM/ODM
Order standard metric steel tube from stock or specify your own OD, wall thickness, length, finish and packaging. We support custom machining parts and precision cnc components made from our tube as added-value services — and the same factory also offers cnc prototype service, cnc turning milling parts and sheet metal fabrication, so tube-based assemblies can be sourced from one supplier.
Quality Assurance
OD, wall thickness, length and surface finish are checked per batch with micrometers, calipers and surface gauges. Mill test certificates can be provided with your order.

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.
