​Specifications & Technical Data

​Key Properties of Our Stainless Steel Coils

​1. Tensile Strength

Stainless steel coils are engineered to withstand extreme mechanical stress:

• ​Grade 304: 515–720 MPa, ideal for ​stainless steel tubing coil in automotive exhaust systems.
• ​Grade 316L: 485–620 MPa, perfect for marine-grade ​stainless steel coil nails and offshore platforms.
• ​Grade 904L: 490–690 MPa, designed for sulfuric acid-resistant ​stainless steel tubing coil in chemical plants.
  These values ensure structural integrity in high-pressure environments.

​2. Bend Strength

Our coils maintain flexibility for precision shaping:

• ​304: Minimum bend radius of 1.5x thickness (suitable for ​stainless steel coil nails in construction).
• ​316L: Bend radius ≤2x thickness (used in ​stainless steel tubing coil for heat exchangers).
• ​420: High hardness allows tight bends (≤1x thickness) for industrial fasteners.

​3. Identification & Marking

Each ​stainless steel coil is laser-etched with:

• ​Grade (e.g., 316L, 904L).
• ​Batch Number for full traceability.
• ​Compliance Marks (ASTM, AISI, JIS).
  This ensures authenticity and adherence to global quality standards like ISO 9001:2015.

​4. Weight Calculation

Calculate coil weight using the formula:
$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times \text{Density (g/cm³)}\times 0.001$
Example: A ​316L stainless steel coil (0.5mm thick, 1.2m x 500m) weighs:
$0.5\times 1.2\times 500\times 8.0\times 0.001=2.4\text{kg}$

​5. Corrosion Resistance & Rust Prevention

While ​stainless steel coils resist rust, improper use can lead to oxidation:

• ​Chemical Exposure: Chlorides or acids degrade passive layers (grade 304 in coastal areas).
• ​Mechanical Damage: Scratches from ​stainless steel coil nails installation expose raw steel.
• ​High-Temperature Oxidation: Prolonged heat (>600°C) weakens chromium oxide layers.
  Our solutions:
• ​Passivation: Enhances corrosion resistance for grades 316L/904L.
• ​Surface Finishes: Brushed or 2B finishes reduce bacterial adhesion in ​stainless steel tubing coil.

​Applications of Stainless Steel Coils

• ​Stainless Steel Tubing Coil: Automotive exhausts, hydraulic systems, and medical equipment.
• ​Stainless Steel Coil Nails: Roofing, HVAC ducting, and industrial machinery assembly.
• ​Other Uses: Kitchen equipment, chemical tanks, and architectural cladding.
