Ideal for stainless steel strip coil fabrication, stainless steel tubing coil 1/2 100 ft systems, and 1 1/4 stainless steel coil roofing nails manufacturing, it combines aesthetic appeal with industrial-grade durability. Trusted by global suppliers, our coils are certified for global compliance and sustainability.

Technical Specifications

Key Performance Attributes

Tensile & Bending Strength

The 316L stainless steel coil delivers a tensile strength of ≥485 MPa, making it ideal for high-stress applications like stainless steel tubing coil 1/2 100 ft systems in chemical plants and offshore platforms. Its austenitic structure ensures excellent ductility (≥40% elongation), enabling complex forming without cracking. The molybdenum content (2-3%) enhances resistance to pitting and crevice corrosion, even in chloride-rich environments.

For bending applications, the alloy’s elongation properties allow tight-radius bends without compromising structural integrity, perfect for architectural cladding and stainless steel strip coil components.

Weight Calculation

Calculate coil weight using:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.98 g/cm³)
Example: A 1.5mm × 1219mm × 50m coil weighs:
1.5 × 1.219 × 50 × 7.98 ≈ 731 kg

Why Does Stainless Steel Rust?

While 316L is highly corrosion-resistant, rust can occur under extreme conditions:

1. Chloride Exposure: Prolonged contact with seawater or de-icing salts degrades the chromium oxide layer.
2. Mechanical Damage: Scratches during fabrication (e.g., 1 1/4 stainless steel coil roofing nails installation) expose raw metal to oxidation.
3. Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in electrolyte-rich environments accelerates oxidation.
4. High-Temperature Oxidation: Exposure above 870°C weakens the passive layer, leading to scaling.

Identification & Traceability

Each coil is laser-marked with:

• Grade: 316L/1.4404
• Batch Code: Linked to MTC (Mill Test Certificate) for full traceability.
• Surface Finish: e.g., 2B (Cold Rolled Matte), Mirror.

Applications

• Industrial Tubing: Stainless steel tubing coil 1/2 100 ft for heat exchangers and hydraulic systems.
• Construction: 1 1/4 stainless steel coil roofing nails for corrosion-resistant fastening in coastal buildings.
• Food Processing: Stainless steel strip coil for hygienic conveyor belts and storage tanks.
• Marine Equipment: Ship components and offshore platforms leveraging 316L’s chloride resistance.
