​Key Performance Attributes

  1. ​Tensile Strength

    • ​Grade 202: Ideal for lightweight structural applications due to balanced strength (620 MPa) and ductility.
    • ​Grade 304: Combines moderate tensile strength (515–685 MPa) with exceptional corrosion resistance, suitable for food processing and architectural uses.
    • ​Grade 316: Enhanced with molybdenum for superior tensile performance (485–620 MPa) in chloride-rich environments like marine and chemical industries.

  2. ​Bending Strength

    • All grades exhibit excellent bendability due to low carbon content (<0.08%) and austenitic microstructure. ​Stainless steel metal rods maintain structural integrity even at 90° bends, minimizing cracking risks.

  3. ​Identification Marking

    • Laser-etched labels include:
      • ​Grade (e.g., 304L, 316L)
      • ​Standard (ASTM/AISI)
      • ​Heat Number for traceability
      • ​Size (OD × WT × Length)
    • Compliant with ISO 9443 and ASTM A480 specifications.

  4. ​Weight Calculation Formula

    • ​For Pipes: Weight (kg/m) = (OD – WT) × WT × 0.0248
    • ​For Rods: Weight (kg/m) = (π × (OD/2)²) × 7.93
    • Example: A 304 stainless steel pipe with 50mm OD and 2mm WT weighs ​2.35 kg/m.

  5. ​Stainless Steel Corrosion: Causes & Prevention

    • ​Chloride Exposure: Prolonged contact with seawater or de-icing salts accelerates pitting in non-molybdenum grades (e.g., 304).
    • ​Mechanical Damage: Scratches or improper handling disrupt the passive chromium oxide layer, leading to localized rust.
    • ​Thermal Stress: Excessive heat (e.g., welding without ​stainless steel tig rod) causes carbide precipitation, reducing corrosion resistance.
    • ​Prevention: Use ​stainless steel filler rod ER316L for welding, apply passivation treatments, and avoid abrasive cleaning tools.
