Robust Stainless Steel Tube Pipe | 304 Industrial Grade

​Product Overview

Our ​stainless steel tube pipe is engineered for industrial applications requiring exceptional durability and corrosion resistance. Manufactured from premium 304-grade stainless steel, this product excels in harsh environments, including chemical processing, oil and gas systems, and structural frameworks. Available in ​corrugated stainless steel tube gas pipe designs for enhanced flexibility and ​cost-effective stainless steel pipes and tubes solutions, our inventory meets ASTM, DIN, and JIS standards, ensuring compliance with global quality benchmarks.

​Mechanical Properties

  1. ​Tensile Strength:

    • ​304 Stainless Steel: Minimum 515 MPa (74,700 psi).
    • ​Cold-Worked Variants: Up to 860 MPa (124,700 psi) for high-pressure applications like ​corrugated stainless steel tube gas pipe systems.
    • This ensures structural integrity in load-bearing frameworks and fluid transport under extreme conditions.

  2. ​Bending Strength:

    • Achieves 1.5× tensile strength (≈773 MPa) due to the austenitic microstructure.
    • Ideal for applications requiring tight-radius bends, such as HVAC ducting and machinery components.

​Identification & Marking Methods

  • ​Laser Etching: Permanent grade markings (e.g., "304," "316L") for traceability.
  • ​Color Coding: PVC sleeves or painted ends to differentiate ​stainless steel tube pipe sizes and grades.
  • ​Certification Tags: Mill Test Reports (MTR) with chemical composition and mechanical data.

​Weight Calculation Formula

For ​cost-effective stainless steel pipes and tubes, weight per meter is calculated as:

Where:

  •  = Outer Diameter (mm)
  •  = Wall Thickness (mm)
    Example: A 100×100 mm square tube with 5 mm thickness weighs ≈11.8 kg/m.

​Why Stainless Steel Rusts?

Despite its corrosion resistance, stainless steel can rust under specific conditions:

  1. ​Chloride Exposure: Chlorine ions in seawater or cleaning agents penetrate the chromium oxide layer, causing pitting corrosion.
  2. ​Mechanical Damage: Scratches or abrasions expose the iron-rich substrate to oxygen, initiating oxidation.
  3. ​Low Oxygen Environments: In stagnant water or enclosed spaces, the passive film cannot self-repair.
  4. ​Galvanic Corrosion: Contact with carbon steel or copper accelerates rusting in humid conditions.

Our 304-grade tubes mitigate these risks with 18–20% chromium and 8–10.5% nickel, ensuring robust passivation and self-healing properties.

 

​Why Choose Our Stainless Steel?

  1. ​Certified Quality: Compliant with ASTM, DIN, and JIS standards for guaranteed performance.
  2. ​Custom Sizes: Tailor-made ​stainless steel tube pipe dimensions to fit unique project needs.
  3. ​Bulk Savings: ​Cost-effective stainless steel pipes and tubes with volume discounts and fast global shipping.
  4. ​Versatility: Suitable for ​corrugated stainless steel tube gas pipe systems, structural frameworks, and sanitary applications.
  5. ​Low Maintenance: Non-porous surfaces reduce cleaning costs and bacterial growth.
