0.16mm Diameter 304 Stainless Steel Spring Wire

TopOne 0.16mm 304 Stainless Spring Wire

 Key Advantages

1. Superior Fatigue Life: Achieves ASTM 12+ grain size, reducing stress points. Proven 300% longer fatigue life in high-cycle applications (>1 million cycles) vs. standard 304 wire.

2. Exceptional Consistency:

   • Ultra-tight diameter tolerance: ±0.01mm at 3mm (40% better than ISO 8458).

   • Minimal lot variation: Elastic Modulus (193 ±3 GPa), Tensile Strength (1850-2100 MPa). Ensures reliable fit and function.

3. Enhanced Corrosion Resistance: Proprietary passivation creates a denser, more uniform protective layer. Passes 72-hour salt spray (ASTM B117) with Class A surface (no pitting), outperforming 304 in harsh environments.

4. Long-Term Reliability & Force Retention: Very low stress relaxation (≤9.5% after 1000 hrs @ 200°C). FEA-validated for >15-year service in critical systems where standard 304 fails.

5. Full OEM Support: Each coil includes detailed metallurgical certification (chemistry, torsion tests). Backed by 30+ years expertise for custom requirements (e.g., creep resistance, cryogenic toughness).
