SAE-1008 Steel Wire Rod: Precision Low-Carbon Solution for Cold-Heading & Wire Manufacturing
SAE-1008 steel wire rod is a low-carbon, high-ductility steel grade engineered for superior cold-forming performance. With a controlled carbon content (≤0.09%) and optimized manganese levels (0.30–0.50%), it delivers exceptional weldability, surface finish, and consistency for high-volume wire product manufacturing. Compliant with ASTM A510 and SAE J403 standards, this wire rod is ideal for automotive fasteners, construction nails, industrial springs, and general hardware applications.
Key Technical Specifications & Dimensional Accuracy
SAE-1008 wire rods are precision-rolled to meet stringent tolerances, ensuring seamless integration with cold-heading and wire-drawing machinery:

| 8.0 | 0.4 | 0.503 | 0.395 | 0.64 |
| 12.0 | 0.4 | 1.131 | 0.888 | 0.80 |
| 16.0 | 0.5 | 2.011 | 1.578 | 0.80 |
Available Sizes: 5.5–16.0 mm (±0.3–0.5mm)
Certifications: ISO 9001, RoHS, REACH, and Mill Test Reports (MTR) available.
Optimized Chemical Composition for Enhanced Formability
SAE-1008’s low-carbon chemistry minimizes work hardening while maintaining structural integrity:
- Carbon (C): ≤0.09% (enhances cold-heading performance)
- Manganese (Mn): 0.30–0.50% (improves strength and hardenability)
- Silicon (Si): ≤0.10% (reduces oxidation during processing)
- Sulfur (S): ≤0.030% (minimizes hot-shortness risks)
- Phosphorus (P): ≤0.020% (prevents brittleness)
- Residuals (Cr/Ni/Cu): ≤0.15–0.25% (ensures purity for welding)
Superior Mechanical Performance
SAE-1008 wire rods are heat-treated to achieve balanced mechanical properties:
- Tensile Strength: 330–440 MPa (47,862–63,816 psi)
- Elongation at Break: ≥20% (50mm gauge length)
- Hardness: 65–85 HRB (Rockwell B Scale)
- Surface Quality: Smooth, scale-free finish (Ra ≤1.6μm)
Industrial Applications & Competitive Advantages
SAE-1008’s versatility makes it indispensable across sectors:
- Automotive: Cold-headed bolts, rivets, and wheel studs.
- Construction: Galvanized nails, fencing wire, and rebar ties.
- Consumer Goods: Springs, paper clips, and zipper components.
- Energy: Cable armoring and transformer winding wires.
Advantages Over Competing Grades:
- Cost Efficiency: 15–20% lower material waste vs. SAE-1018.
- Machining Speed: Compatible with high-speed wire drawing (≤30 m/s).
- Corrosion Resistance: Accepts electroplating (zinc, nickel) without pretreatment.
Manufacturing Excellence & Quality Assurance
Produced via controlled hot-rolling processes, SAE-1008 wire rods undergo rigorous testing:
- In-line Inspection: Laser gauging for diameter consistency (±0.5% tolerance).
- Surface Defect Detection: Eddy current testing (ECT) for cracks and seams.
- Spheroidization Annealing: Optional heat treatment for improved ductility (≤4% elongation gain).
Why Choose SAE-1008 Wire Rods?
With a density of 7.85 g/cm³ and thermal conductivity of 49.8 W/m·K, SAE-1008 ensures efficient heat dissipation during high-speed processing. Its low yield strength (≥180 MPa) reduces press wear, while compliance with EN 10218-2 and JIS G3505 guarantees global acceptance.
