Key Features

  1. Superior Corrosion Resistance:

    • Molybdenum content (2-3%) prevents pitting in chloride, sulfuric acid, and marine environments.
    • Low carbon (≤0.03%) minimizes carbide precipitation during welding.

  2. High-Temperature Performance:

    • Retains strength up to 925°C, suitable for heat exchangers and boilers.

  3. Surface Finishes:

    • Sanitary finishes: Mirror polish, pickling, or brushed surfaces for food/pharmaceutical compliance.
    • Standard finishes: 2B, BA, or annealed.

  4. Certifications:

    • ISO 9001, ASTM, ASME, and NABL test reports.

Technical Details

Tensile & Bend Strength

316L stainless steel exhibits a tensile strength of ≥485 MPa and yield strength of ≥170 MPa, ensuring structural integrity under high stress. Its ductility (≥40% elongation) allows bending without fracture, making it ideal for complex piping layouts.

 

Weight Calculation Formula

Weight per meter (kg/m) = (OD – Wall Thickness) × Wall Thickness × 0.0248
Example: For a schedule 40s stainless steel pipe dimensions (OD 6.625", thickness 0.28"):
Weight = (6.625 – 0.28) × 0.28 × 0.0248 ≈ 19.16 kg/m.

 

Identification Marking

All pipes are laser-etched with:

  • ASTM/ASME standard (e.g., ASTM A312).
  • Grade (316L), OD, thickness, heat number, and manufacturer’s logo.

Why Does Stainless Steel Rust?

While 316L resists rust better than 304, prolonged exposure to:

  1. Chloride-rich environments (e.g., seawater) exceeding 500 ppm.
  2. Mechanical damage (scratches or improper welding) disrupting the chromium oxide layer.
  3. High temperatures (>925°C) causing oxidation.

Price & Packaging

  • pipe stainless steel price: Starts at $3.50/kg for bulk orders (varies by size, schedule, and finish).
  • Packaging: Wooden crates, plastic wrapping, or hexagonal bundles with waterproof layers.
  • Delivery: Global shipping with fumigation certificates and material test reports.
