Key Attributes

  1. Corrosion Resistance: Enhanced by 18–20% chromium (304) and 16–18% chromium + 2–3% molybdenum (316L), ideal for chloride-rich environments like marine or chemical plants.
  2. High-Temperature Stability: Retains structural integrity up to 870°C (304) and 843°C (316L), suitable for heat exchangers and exhaust systems.
  3. Flexibility: Compatible with stainless steel pipe fittings near me and stainless steel flexible hose pipe installations, ensuring leak-proof joints and adaptability.

Detailed Performance Characteristics

Tensile & Bend Strength

  • Tensile Strength:
    • 304: Minimum 515 MPa, making it robust for hydraulic systems and structural supports.
    • 316L: 485 MPa tensile strength with superior stress corrosion cracking resistance, ideal for acidic or saline environments.
  • Bend Strength: Both grades exhibit excellent ductility due to austenitic microstructure. 3 inch stainless steel pipe maintains roundness even under high-pressure bending, critical for plumbing and HVAC systems.

Identification Methods

  • Laser Etching/Stamping: Permanent markings include grade (e.g., "304" or "316L"), OD, thickness, and heat number per ASTM A480.
  • Certification: Mill Test Reports (MTRs) validate chemical composition and mechanical properties for traceability.

Weight Calculation

Use the formula:

Example: A 3 inch stainless steel pipe (76.2 mm OD, 3 mm WT) weighs ~5.4 kg/m.

Causes of Stainless Steel Rust

Despite its name, rust can occur under:

  1. Chloride Exposure: High chloride concentrations (e.g., seawater) disrupt the chromium oxide layer, causing pitting.
  2. Mechanical Damage: Scratches or abrasions expose raw metal to oxidation.
  3. Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in conductive environments accelerates degradation.
  4. Improper Welding: Carbon precipitation in heat-affected zones reduces corrosion resistance, mitigated by using low-carbon 316L.
