Manufacturing Processes for High Temperature Nickel Alloy Springs Machining Service
Our high temperature nickel alloy springs machining service is built around stable, repeatable processes designed for tough alloys like Inconel, Hastelloy, Nimonic, Waspaloy, and René 41.
CNC Precision Wire Coiling for Nickel-Based Alloys
We use CNC precision wire coiling to form compression, extension, torsion, and custom coil springs from nickel-based superalloys. Tight control of feed, pitch, and diameter gives you:
- Consistent spring rate and load
- Stable geometry, even on small-batch or complex forms
Our coiling setups are optimized specifically for high temperature superalloy springs, including Inconel spring machining and Waspaloy extension springs.
Hot and Cold Setting for Relaxation Control
To keep relaxation-resistant nickel alloy springs stable at temperature, we:
- Hot set springs to simulate real operating conditions
- Cold set where needed for tighter load tolerance
This controls creep and load loss for demanding uses like gas turbine hot section springs and high temp valve springs.
End Grinding and Surface Conditioning
We precision grind spring ends to improve seating and load distribution, especially for compression and wave springs. Surface conditioning removes burrs and sharp edges to:
- Cut stress concentrations
- Improve fatigue performance
For more advanced surface prep and coatings, we integrate dedicated surface treatment and finishing processes as needed.
Solution & Precipitation Heat Treatment in Vacuum Furnaces
All critical nickel alloy springs go through vacuum heat treatment with:
- Solution treatment for microstructure control
- Precipitation hardening for strength and fatigue life
This is essential for Inconel 718 helical springs, René 41 hot coiled springs, and other aerospace-grade parts. Our controlled cycles give repeatable hardness and mechanical properties across each batch.
Shot Peening & Stress Relief
We apply shot peening and controlled stress relief to boost high-cycle fatigue life:
- Induces beneficial compressive surface stresses
- Reduces risk of crack initiation in high-vibration environments
This is key for turbine seal springs, aerospace superalloy springs, and high performance exhaust springs in motorsport.
Passivation, Electro-Polishing & Anti-Corrosion Finishing
To improve corrosion resistant nickel springs, we offer:
- Chemical passivation for clean, passive surfaces
- Electro-polishing for smoother, lower-friction coils
- Optional anti-corrosion coatings tailored to petrochemical, subsea, or exhaust environments
These finishing steps tie directly into our broader surface treatment services for nickel-based components.
Non-Destructive Testing & Dimensional Inspection
Every critical spring run is backed by non-destructive testing (NDT) and inspection:
- MT (magnetic particle) and PT (penetrant testing) for surface defects
- X-ray or other methods where geometry demands it
- Full dimensional checks for OD, free length, pitch, and load
We follow strict testing workflows aligned with our testing and quality control procedures to support AS9100 nickel alloy spring supplier requirements and high-reliability industries.

Performance & Technical Advantages of High Temperature Nickel Alloy Springs
Our high temperature nickel alloy springs machining service is built for tough, high-heat environments where failure is not an option. We design and machine each spring to hold load, resist creep, and stay stable through extreme cycles.
Key Performance Benefits
- Relaxation resistance & load retention
Our Inconel, Hastelloy, Nimonic, René 41, and Waspaloy springs are engineered to keep their load over thousands of hours at 600–1200 °C. That means fewer re-torques, fewer shutdowns, and more predictable system behavior. - High cycle fatigue performance
We combine controlled coiling, precision heat treatment, and shot peening to deliver nickel alloy springs that survive very high cycle counts under dynamic loading. Ideal for turbine seals, combustor hardware, and high-speed exhaust systems. - Creep resistance under high load
For constant high load at temperature, we choose the right superalloy and heat treatment route so the spring keeps its working height and rate over time instead of slowly deforming. - Dimensional stability in thermal cycling
Our vacuum heat-treated nickel-based alloy coil springs are made to handle repeated start-up/shut-down cycles with minimal drift in free length, pitch, or load curve. - Predictable behavior under vibration
We control surface finish, residual stress, and geometry so springs respond consistently in high-vibration environments like gas turbines, motorsport exhausts, and subsea valves.
