Titanium Grade 5 Belleville disc springs
EN 16983ASTM B265
Titanium Grade 5 disc springs put higher strength than commercially pure titanium at low density into a flexing preload element. Working force, installed height and final material condition define the part more usefully than free diameter alone.

Heat Treatment
AnnealedAnnealing reduces working stresses and restores ductility, with atmosphere and surface control limiting contamination during heating.
What we can make in Titanium Grade 5
Single disc
Use under a fastener or in a preload mechanism when a short axial space must provide spring force. Select by load at working deflection, not by bore and outside diameter alone.
Series stack
Alternate disc orientation when a joint needs more travel to accommodate thermal movement or seating loss. Total travel increases at approximately the single-disc load; guides keep the stack aligned.
Parallel stack
Nest discs in the same orientation when the available travel is small but more spring force is needed. Load rises at approximately the single-disc deflection, with friction affecting the real load-deflection response.

Manufacturing route
Disc blanks are cut and formed to the required cone height; thickness and edge quality control stress distribution through the working travel.
Heat treatment & final condition
Forming and thermal processing require contamination control. The final surface is cleaned before dimensional and material acceptance.
Working performance
The alloy’s elastic modulus and forming response require a dedicated load–deflection design. A steel spring rating cannot be carried over to the same-size reactive-metal disc or ring.
Where Titanium Grade 5 fits — and what matters
Industrial Machinery & Automation
Machine frames and positioning fixturesTitanium Grade 5 disc spring / belleville washers form preload stacks in the bolted mounts of machine frames and positioning fixtures. Working deflection allows the stack to accommodate movement while maintaining the designed spring force. Alignment, operating cycles and replacement access define the working interface.
Pumps, Valves & OEM
Actuator mounts and pump baseplatesTitanium Grade 5 disc spring / belleville washers form preload stacks in the bolted mounts of actuator mounts and pump baseplates. Working deflection allows the stack to accommodate movement while maintaining the designed spring force. Repeated maintenance makes fit, engagement and access part of the component specification.
Automotive & EV Manufacturing Equipment
Assembly fixtures and test-rig framesTitanium Grade 5 disc spring / belleville washers form preload stacks in the bolted mounts of assembly fixtures and test-rig frames. Working deflection allows the stack to accommodate movement while maintaining the designed spring force. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Same disc spring. Different material priorities.
Titanium Grade 5 material dataInconel X-750
Age-hardened strength and a choice of hot-service heat treatments.
- Connection priority
- Force at working deflection and relaxation during dwell
- Spring treatment versus bolting treatment
- X-750 has several heat-treatment routes. The route for retained spring force is selected around relaxation and working stress; a bolting strength requirement calls for its own specified condition. At the loaded disc faces and stack contact edges, the relevant metal temperature can differ from the process or furnace set point.
Inconel 718
Precipitation-hardened strength for compact, highly loaded connections.
- Connection priority
- Force at working deflection and relaxation during dwell
- Strength after aging
- Machine-stock properties and final aged properties describe different states. The final heat-treatment lot and mechanical results establish the strength available in the installed part. At the loaded disc faces and stack contact edges, the relevant metal temperature can differ from the process or furnace set point.
Inconel 625
Solid-solution strength and resistance to aggressive process liquids.
- Connection priority
- Force at working deflection and relaxation during dwell
- Annealed or solution-annealed 625
- The delivery condition affects strength and high-temperature response. Keep the specified condition with the component’s mechanical acceptance; 718-style aging is not the strengthening route for 625. Include liquid retained at the loaded disc faces and stack contact edges in the exposure description.

Questions about Titanium Grade 5 disc spring / belleville washers
Can an alloy change preserve the same disc-spring rating?
Elastic modulus, yield behaviour and final condition influence the load–deflection curve. Recalculate and verify the working response for the selected alloy rather than carrying over a same-size steel disc’s rating.
