Key Features & Applications
1. Cold-Rolled Excellence
Cold-rolled stainless steel coils offer ultra-smooth surfaces (e.g., 2B, BA finishes) with tight tolerances (±1%), ideal for stainless steel coil heat exchanger components requiring minimal friction and high thermal conductivity. This process enhances hardness (≤220 HV) while maintaining ductility for bending and welding.
2. Food-Grade Safety
316L’s low carbon content (≤0.03%) prevents carbide precipitation during welding, making it safe for food processing equipment, dairy tanks, and pharmaceutical machinery. Its molybdenum content (2–3%) resists chlorides in saline or acidic environments.
3. Corrosion Resistance
The chromium oxide layer (Cr ≥16%) provides self-healing protection against oxidation, while molybdenum combats pitting in chloride-rich settings like marine stainless steel siding nails coil applications.
Performance & Durability
1. Tensile & Bend Strength
- Tensile Strength: With ≥520 MPa, these coils withstand high-pressure environments, such as industrial boilers or heat exchangers.
- Bend Strength: The elongation rate (≥40%) ensures flexibility for forming complex shapes without cracking.
2. Weight Calculation
Use the formula:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × 7.98
Example: A 0.3mm × 1219mm × 2000mm coil weighs ≈5.7 kg/m².
3. Rust Prevention
Despite 316L’s superior corrosion resistance, rust may occur due to:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts.
- Surface Contamination: Iron particles from improper handling tools.
- High-Temperature Oxidation: Continuous use above 427°C (800°F) degrades the passive layer.
Certifications & Customization
- Standards: ASTM A240, AISI 316L, JIS G4303.
- Processing: Custom cutting, decoiling, and edge treatments (slit or mill edge).
- Packaging: PVC film + fumigated wooden frames for international shipping.
