Product Description
High-Temperature Resistant Helical Spring
Engineered for 1200°C thermal stability in power generation and automotive applications. Our precision-engineered helical spring maintains dimensional stability, elastic performance, and fatigue resistance in extreme thermal environments from 200°C to 1200°C.
Material Options
Material selection is critical to thermal resilience, with options tailored to specific temperature thresholds:
| Material | Temperature Range | Key Properties | Applications |
|---|---|---|---|
| Inconel® X-750 (UNS N07750) | Up to 800°C | Maintains 85% tensile strength at 800°C, 10⁵ hour creep rupture strength of 150MPa at 700°C | Gas turbine combustors, exhaust systems |
| Haynes® 282® (UNS N07282) | Up to 1000°C | Superior oxidation resistance (≤0.01mm/year weight loss at 980°C), thermal fatigue resistance | Industrial furnace door mechanisms |
| Nimonic® 90 (UNS N07090) | 200°C to 800°C | <2% permanent set after 10⁴ thermal cycles, optimized for cyclic thermal loading | Automotive turbocharger wastegates |
| Tungsten alloy (W-2%ThO₂) | Up to 1200°C | 310MPa yield strength at 1000°C | Nuclear reactor control rods |
Design Features
Our design process integrates multi-physics FEA (ANSYS Mechanical Thermal) to simulate thermal expansion, creep deformation, and stress relaxation. Spring geometry is optimized with:
- Variable pitch coils to compensate for differential thermal expansion (±0.02mm tolerance on coil spacing)
- Tapered wire diameters (1.5-8mm) to reduce stress concentration at coil interfaces
- Heat-treated end configurations (ground, squared, or looped) to maintain load distribution under thermal cycling
Manufacturing Process
- Vacuum induction melting to minimize impurity levels (<0.005% sulfur)
- Solution annealing (1050°C for Inconel alloys) followed by age hardening to precipitate γ' phase strengthening
- Shot peening with 0.1mm zirconia media to induce 600MPa compressive residual stress, extending fatigue life by 300%
- Plasma spray coating (MCrAlY, 50-100μm thickness) for enhanced oxidation resistance in cyclic high-temperature environments
Performance Validation
Adheres to stringent industry standards:
- ISO 13920 Class 0 fatigue testing: 10⁸ cycles at 70% rated load with <1% load loss
- ASTM E290 creep testing: <0.2% plastic deformation after 1000 hours at 800°C/500N load
- Thermal shock testing (MIL-STD-810H Method 503.7): 100 cycles from -50°C to 1000°C with no structural failure
- Oxidation resistance per ASTM G54: <0.1mg/cm² weight gain after 1000 hours at 900°C
Field Performance
Field applications demonstrate exceptional reliability:
- Power generation client reduced turbine spring replacements by 75% with Inconel X-750 springs
- Automotive OEM achieved 1.2 million km turbocharger durability with Nimonic 90 wastegate springs
- Semiconductor furnace manufacturer reported zero spring failures in 3-year continuous operation at 1100°C
Backed by ISO 9001:2015 and AS9100D certifications, we provide full material traceability (heat lot certificates, test reports) and custom engineering support—including FEA thermal modeling and application-specific material selection—to meet your exact temperature, load, and environmental requirements.
