Detailed Performance Characteristics

1. Tensile Strength & Bendability

Tensile strength (≥520 MPa) ensures structural integrity under high stress, while elongation (≥40%) allows for deep drawing and complex forming without cracking. The alloy’s low carbon content (≤0.07%) enhances weldability and reduces carbide precipitation, maintaining corrosion resistance post-fabrication. For stainless steel tube coil applications, this enables seamless bending into helical or nested configurations for heat exchangers and hydraulic systems.

 

2. Why Stainless Steel Can Rust?

Despite its chromium oxide barrier, 304 stainless steel may corrode in chloride-rich environments (e.g., coastal areas or chemical plants). Factors include:

 

  • Chloride-Induced Pitting: Chloride ions penetrate the passive layer, causing localized corrosion.
  • Mechanical Damage: Scratches or abrasions expose untreated steel to oxidation.
  • Improper Cleaning: Residual iron particles or acidic cleaners accelerate rusting.
    Regular maintenance with non-abrasive cleaners preserves the mirror finish.

3. Weight Calculation Formula

Calculate coil weight using:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³).
Example: A 1.0 mm × 1,219 mm × 100 m coil weighs ≈970 kg.

 

4. Identification & Marking

Coils are laser-marked with:

  • Grade (304/304L)
  • Thickness/Width
  • Surface Finish (e.g., "BA" for Bright Annealed)
  • Batch Number for traceability.

Applications

  • Architectural: Elevator panels, column covers (mirror finish for reflective aesthetics).
  • Industrial: Stainless steel coiled pipe for heat exchangers, chemical tanks.
  • Consumer Goods: Kitchen sinks, appliance trim.
