Product Description
Detailed Specifications & Features
SUNZO High-Temperature Disc Springs: Inconel718 & Inconel X-750 Engineered Solutions for Extreme Thermal Environments
In extreme temperature environments where conventional spring materials fail, SUNZO high-temperature disc springs—precision-engineered from Inconel718 and Inconel X-750 superalloys—deliver exceptional mechanical stability and thermal resilience.
Material Performance Specifications
These nickel-chromium-based superalloys are specifically formulated to maintain structural integrity across extreme temperature ranges:
- Inconel718: Operates reliably up to 650°C (1202°F) with minimal creep deformation
- Inconel X-750: Extends performance to 750°C (1382°F) under cyclic loading conditions
- Oxidation Resistance: ASTM G111 testing shows <0.01mm/year material loss at 600°C
- Thermal Strength: Maintains 85% of room-temperature tensile strength at 500°C
Engineering Design & Performance
The unique conical design of SUNZO's high-temperature disc springs—featuring optimized dish height-to-thickness ratios (0.6-1.0) and precision-toleranced geometries (±0.02mm)—enables stable force-deflection characteristics even under thermal cycling.
Inconel718: Modulus of elasticity of 206 GPa with fatigue life exceeding 10⁶ cycles at 70% of yield strength (1,240 MPa ultimate tensile strength)
Inconel X-750: Enhanced creep resistance (0.1% creep strain after 1,000 hours at 650°C/620 MPa) due to γ' precipitate strengthening
Key Applications
- Aerospace Propulsion: Turbine engine thrust reversers and exhaust nozzle actuators utilizing Inconel718 springs for sustained operation at 600°C
- Nuclear Energy: Control rod drive mechanisms employing Inconel X-750 springs to maintain critical preload in reactor cores (radiation resistance up to 10⁸ rads)
- Industrial Furnaces: High-temperature conveyor systems using Inconel718 disc springs in thermal expansion compensation assemblies
- Gas Turbines: Combustion chamber liners with Inconel X-750 springs providing constant sealing force during thermal transients
Manufacturing & Quality Assurance
Each spring undergoes specialized heat treatment (solution annealing at 980°C followed by aging cycles) to optimize grain structure and precipitate formation. Manufacturing processes include CNC precision stamping (tolerance ±0.05mm) and ultrasonic cleaning to remove surface contaminants.
Custom Engineering Options
- Coating Systems: Aluminum diffusion coatings for enhanced oxidation resistance up to 800°C
- Specialized Testing: Thermal cycling validation (-200°C to 700°C) and helium leak testing for nuclear applications
- Non-destructive Evaluation: Eddy current inspection and dye penetrant testing per ASME BPVC Section V
Backed by ISO 9001:2015 certification and full material traceability (EN 10204 3.1), SUNZO high-temperature disc springs provide engineers with reliable elastic solutions for the most demanding thermal environments. Our technical team offers application-specific design support, including FEA thermal stress analysis and material selection guidance.
