High Temperature Belleville Disc Springs made of high temperature resistant material as Inconel 718 , 750 , Nimonic 90 , these Belleville Disc Springs are applied for high temperature from -50°C up to +500°C) environment, and ultra high temperature (from -250°C up to +700°C) environment.
Description
High Temperature Disc Springs are heat-resistant Belleville disc springs designed to maintain stable load, deflection and fatigue performance in elevated-temperature environments. HEGONG SPRING manufactures custom high temp disc springs using Inconel 718, Inconel X-750, Nimonic 90, H13 and other high-temperature alloy materials for valves, heat exchangers, boilers, industrial furnaces, petrochemical equipment and power systems.
Our high temperature Belleville disc springs are designed and manufactured according to DIN 2092, DIN 2093, GB/T 1972-2005 and ISO 19690. Standard and custom sizes are available with outer diameters from 6mm to 600mm and thickness from 0.2mm to 24mm. High Temperature Disc Springs are widely used in Valves, Heat Exchangers, Boilers, Industrial Furnaces & Ovens, Cryogenic Technology, Special Chemical circumstances, etc.
The engineers of HEGONG SPRING ® are pleased to design the springs for the specific applications together with the customer’s R&D department. Be free to contact with our engineers. Tech@DiscSpringsMFG.com.
In high-temperature equipment, ordinary spring materials may lose load, deform or suffer fatigue failure after long-term operation. High temperature resistant springs are selected to provide stable preload, compensate thermal expansion and maintain reliable force in compact installation spaces.
Compared with coil springs, high temperature disc springs provide high load capacity within a short axial space. They are widely used where heat, pressure, vibration, corrosion or limited installation height create demanding working conditions.
Common applications include:
Industrial valves and valve actuators
Heat exchangers and boilers
Petrochemical equipment
Industrial furnaces and ovens
Power generation systems
Turbines and high-temperature bolting systems
Chemical processing equipment
Special machinery working under thermal load

Features and Applications of High-temperature Disc Springs
When selecting high temperature disc springs, buyers should confirm the working temperature, load requirement, deflection range, installation space, corrosion condition and whether the spring will work under static or dynamic loading.
For high-temperature valve assemblies, load retention and fatigue life are usually more important than only the maximum temperature rating. For chemical, offshore or petrochemical environments, Inconel disc springs or other corrosion resistant disc springs may be required.
Please provide the following parameters for engineering support:
| Required Parameter | Example |
|---|---|
| Outer diameter / inner diameter | OD, ID |
| Thickness and free height | t, h0 |
| Working temperature | Continuous temperature and peak temperature |
| Required load | Load at specific deflection |
| Working environment | Heat, steam, chemical, salt spray or vibration |
| Installation method | Single disc spring or stacked arrangement |
| Material requirement | Inconel 718, Inconel X-750, Nimonic 90 or other alloy |
| Standard requirement | DIN 2093, GB/T 1972, ISO 19690 or custom drawing |
