Extended Technical Insights
Tensile & Bending Strength
Half-hard 410/420 grades achieve tensile strengths up to 950 MPa, optimized for high-stress applications like securing metal siding to wooden frames. The martensitic stainless steel coil structure enhances resistance to deformation under load, critical for roofing and industrial HVAC systems. Cold-rolled processing ensures uniform grain flow, while heat treatment (quenching at 980–1050°C) stabilizes hardness and ductility balance.
For rewinding stainless steel coils, precision slitting (0.2–6mm tolerance) guarantees consistent nail alignment, reducing jamming risks in pneumatic tools.
Identification & Weight Calculation
- Chemical Marking: Laser-etched labels (e.g., "ASTM A666") on collation wires for traceability.
- Weight Formula:
- Single Nail Weight (g) = (π × (D/2)² × L × Density) / 1000
- Density: 7.75 g/cm³ (martensitic grades), 7.93 g/cm³ (austenitic grades).
Example: A 3.0mm × 50mm nail weighs ≈ 2.78g, with 2000 pcs/coil ≈ 5.56kg.
Why Stainless Steel Rusts – Causes & Prevention
While martensitic stainless steel coil nails resist corrosion better than carbon steel, rust can occur under:
- Chloride Exposure: Coastal environments degrade passive chromium oxide layers. Grade 430 is prone to pitting vs. 410/420’s superior chloride resistance.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., aluminum) accelerates oxidation. Insulate with nylon washers or vinyl coatings.
- Mechanical Damage: Scratches from improper handling expose raw steel. Use nylon-tipped tools during installation.
- Low Chromium Content: Grades below 12% Cr (e.g., 201) lack sufficient passivation. Our nails use 16–18% Cr for enhanced durability.
Applications of Stainless Steel Coils
- Roofing & Siding: Rewinding stainless steel coils into collated nails (15°–34°) for rapid installation of metal sheets.
- HVAC Systems: Martensitic stainless steel coil components in heat exchangers, combining thermal stability (up to 800°C) with crevice corrosion resistance.
- Structural Engineering: High-strength nails for securing steel beams, pallets, and industrial containers.
