Rust-Proof 304 Stainless Steel Pipe Corrosion Resistant Seamless Tube for Chemical Industry
Product Overview

Our precision seamless 304 stainless steel tubes are specially manufactured for aerospace, instrumentation, and high-performance industrial systems requiring excellent corrosion resistance, dimensional accuracy, and structural stability.

Made from premium ASTM 304 stainless steel, these thin-wall tubes feature:

  • Thickness: 0.3mm–3mm
  • OD Range: 6mm–50mm
  • Surface: Bright Annealed / Polished
  • Process: Hot Rolled + Precision Cold Drawn
  • Type: Seamless

With high chromium and nickel content, 304 stainless steel offers strong oxidation resistance, formability, and clean internal surfaces for demanding fluid and gas transfer systems.


Cause

In aerospace and precision manufacturing, standard stainless steel tubes often face:

  • Poor dimensional tolerance
  • Surface oxidation after welding
  • Internal weld seam weakness
  • Low pressure resistance
  • Inconsistent wall thickness in thin-wall tubing

These issues can affect assembly precision, system safety, and service life.


Solution

Our seamless 304 stainless steel tubes solve these challenges through:

  • Seamless manufacturing for higher pressure resistance
  • Precision tolerance control up to ±0.05mm
  • Bright annealed smooth inner wall
  • Strict ASTM/EN quality inspection
  • Optional custom cutting and finishing

This makes them ideal for aerospace hydraulic lines, instrumentation tubing, and high-purity transport systems.

Application

Widely used in:

  • Aerospace hydraulic tubing
  • Aircraft fuel systems
  • Precision instrumentation
  • Medical equipment
  • Semiconductor gas lines
  • Chemical transfer systems
  • High-pressure fluid pipelines


How It Works

304 stainless steel contains over 18% chromium and 8% nickel, forming a passive oxide layer on the surface.

This protective layer:

  • Prevents corrosion
  • Improves oxidation resistance
  • Extends service life under harsh environments

Seamless construction eliminates weld defects and increases structural integrity under pressure and vibration.


How To Choose

When selecting aerospace stainless steel tubing, consider:

1. Wall Thickness
  • Ultra-thin systems: 0.3–1mm
  • Pressure applications: 1–3mm
2. Tolerance

Choose precision tubes with:

  • OD tolerance ≤ ±0.05mm
3. Surface Finish

Recommended:

  • Bright annealed for clean systems
  • Polished for visible applications
4. Standard

Check required standards:

  • ASTM A213
  • ASTM A269
  • AMS / Aerospace specific requirements

FAQ
1. Is 304 stainless steel suitable for aerospace?

Yes. 304 stainless steel is widely used in aerospace auxiliary systems, instrumentation, and fluid transfer lines due to corrosion resistance and strength.

2. What is the difference between seamless and welded tube?

Seamless tubes have no weld line, offering better pressure resistance, uniform wall thickness, and higher reliability.

3. Can you provide custom sizes?

Yes, custom OD, thickness, length, and surface finish are available.

4. What certificates do you provide?

We can provide:

  • EN10204 3.1
  • MTC
  • PMI
  • Third-party inspection
5. What is your MOQ?

MOQ usually starts from 100kg, depending on size and customization.
