Supplier's note

1. Technical Breakthroughs:

   • High Carbon Content: Enables unmatched tensile strength for heavy-duty springs.
   • Dual Standard Compliance: JIS/DIN certification ensures seamless integration into global supply chains.
   • Precision Coiling: Drawn finish reduces surface defects by 20% compared to traditional wire, enhancing spring longevity.

2. Optimal Version Selection:

   • Base Model: Ideal for general spring applications (e.g., automotive seating) requiring cost-effective solutions.
   • Advanced Model: Recommended for heavy machinery components (e.g., industrial valves) needing 15% higher fatigue resistance.
   • Pro Model: Tailored for aerospace or high-stress environments (e.g., turbine springs) where 30% superior tensile strength and 10^8 cycles durability are critical.

With the Pro Model’s 2,340 MPa tensile strength, you can design springs capable of withstanding extreme pressures found in hydraulic systems. Pair this with its 55–60 HRC hardness to ensure minimal deformation over time, directly boosting equipment reliability.

Note: Specifications are based on standard grades SWA/SWB/SWC and may vary slightly by exact grade (e.g., 72A/82B).
