Key Properties of Our Stainless Steel Coils
1. Tensile Strength
Stainless steel coil exhibits superior tensile strength, ensuring durability in demanding applications:
- Grade 304: 515–720 MPa (ideal for structural components in construction).
- Grade 316L: 485–620 MPa (excellent for stainless steel coil heat exchanger systems exposed to chlorides).
- Grade 904L: 490–690 MPa (resistant to sulfuric acid and seawater environments).
This strength makes our coils suitable for stainless steel coil tubing in high-pressure industrial pipelines and HVAC systems.
2. Bend Strength
Our coils maintain structural integrity even under extreme bending:
- 304: Minimum bend radius of 1.5x thickness (suitable for stainless steel coil tubing in automotive exhausts).
- 316L: Bend radius ≤2x thickness (perfect for marine applications like heat exchanger tubes).
This flexibility ensures seamless fabrication for complex shapes without cracking.
3. Identification & Marking
Each stainless steel coil is laser-etched with:
- Grade (e.g., 316L, 904L).
- Production Batch Number for traceability.
- ASTM/EN/JIS Standards compliance.
This guarantees authenticity and aligns with ISO 9001 and SGS certifications.
4. Weight Calculation
Use the formula to estimate coil weight accurately:
Example: A 316L stainless steel coil (2mm thick, 1m x 3m) weighs:
5. Corrosion Resistance & Rust Prevention
While stainless steel coil heat exchanger systems are corrosion-resistant, rust can occur under specific conditions:
- Chloride Exposure: Coastal or chemical environments degrade passive layers (e.g., grade 304 in saltwater).
- Mechanical Damage: Scratches or abrasions expose raw steel to oxidation.
- High-Temperature Oxidation: Prolonged exposure above 600°C weakens chromium oxide layers.
Our solutions include: - Passivation: Enhances chromium oxide layers for grade 316L/904L.
- Surface Finishes: Mirror or brushed finishes reduce crevice corrosion risks.
Applications of Stainless Steel Coils
- Stainless Steel Coil Tubing: Used in oil/gas pipelines, automotive exhausts, and medical equipment.
- Stainless Steel Coil Heat Exchanger: Ideal for HVAC systems, chemical reactors, and marine cooling units.
