Detailed Specifications & Features
High-Carbon Steel Compression Spring: Engineered Strength for Heavy-Duty Industrial Applications
In heavy-duty industrial environments—from construction machinery to commercial vehicle braking systems—compression springs must deliver exceptional tensile strength, load-bearing capacity, and fatigue resistance to ensure operational safety and equipment longevity.
Material & Performance Specifications
| Material Standards | Premium-grade high-carbon steel alloys (ASTM A228 and EN 10270-1) |
|---|---|
| Tensile Strength | Up to 2200 MPa |
| Hardness Rating | 45-50 HRC |
| Static Load Capacity | Exceeding 50 kN |
| Dynamic Cyclic Loads | 25 kN at 10 Hz without permanent deformation |
Engineering & Design Excellence
Our engineering process integrates advanced CAD (SolidWorks 2024) with FEA (ANSYS Mechanical) simulations to optimize coil geometry, pitch distribution, and end configurations. This precision design ensures load-deflection linearity within ±3% tolerance across the working range, while minimizing stress concentrations at coil interfaces.
Our heavy-duty valve springs feature a progressive pitch design that reduces resonant frequency by 22% compared to standard uniform-pitch springs, preventing harmonic vibration failures in high-speed machinery.
Manufacturing Process
- 5-axis CNC coiling machines (Torsion Tech TT-8000) with sub-millimeter precision (±0.01mm wire diameter control)
- Automated in-process monitoring throughout production
- Proprietary heat treatment cycle: oil quenching at 860°C followed by tempering at 420°C for 2 hours
- Uniform martensitic microstructure enhances fatigue life by 40%
- Validated through 10⁶ cycle testing at 80% of yield strength per ISO 10243 standards
- Post-treatment shot peening with 0.2mm steel media to induce compressive residual stress
Quality Assurance
- 100% load testing using 100kN servo-hydraulic test frames
- Ultrasonic flaw detection for material integrity
- Dimensional inspection via CMM (Coordinate Measuring Machine) with ±0.005mm accuracy
- Full traceability to raw material lot with 3.1.B material certificates
- Compliance with ISO 9001:2015 and automotive IATF 16949 standards
