Key Attributes & Performance
Tensile & Bend Strength
AISI 201 offers exceptional tensile strength (700–850 MPa) due to its high manganese and nitrogen content, making it ideal for structural applications like stainless steel pipe coil systems. Its superior ductility (40–55% elongation) ensures resistance to cracking during cold forming. AISI 410, with moderate tensile strength (450–650 MPa), excels in high-stress environments such as stainless steel heating coil units, where thermal cycling and mechanical wear are common. The Hairline Finish variant combines aesthetic appeal with functional durability, achieving 650–800 MPa tensile strength for applications like stainless steel coil siding nails and architectural accents.
Weight Calculation
The weight of a stainless steel coil can be calculated using the formula:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³)
For example, a 0.4mm × 1000mm × 2000mm coil weighs approximately 6.34 kg. Advanced tools like the BS Stainless Coil Calculator simplify this process, ensuring precision for custom orders.
Why Stainless Steel Rusts
While stainless steel is inherently corrosion-resistant, improper handling or environmental factors can lead to surface oxidation. Common causes include:
- Chloride Exposure: Saltwater or de-icing agents degrade the chromium oxide layer.
- Mechanical Damage: Scratches or abrasions expose raw metal to moisture.
- Low-Quality Alloys: Substandard chromium/nickel ratios reduce corrosion resistance.
Our coils, crafted with ≥10.5% chromium and optimized nickel/molybdenum ratios, mitigate these risks through passivation treatments and rigorous quality checks.
Identification & Marking
Each coil is laser-etched with:
- Grade (AISI 201/410)
- Batch Number (for traceability)
- Surface Finish (e.g., 2B, Hairline)
- Dimensions (thickness/width/length)
Certifications (ISO 9001, ASTM A666) and third-party inspection reports (SGS) ensure compliance with global standards.
