High temperature resistant disc springs
High-temperature disc springs are high-performance elastic components designed specifically for operation in environments with continuous high temperatures or severe temperature cycling. While inheriting the advantages of high load density and compact space of disc springs, they utilize special high-temperature alloys and optimized heat treatment processes to ensure stable elastic force and excellent anti-relaxation and anti-creep properties even at temperatures up to 650°C or higher. They are key components in cutting-edge fields such as high-temperature valves, aerospace, and energy and power systems.
We specialize in solving the challenges of softening, stress relaxation, and oxidation failure in elastic components caused by high temperatures. From high-temperature material databases and thermodynamic simulations to specialized heat treatments, we provide complete solutions to ensure the long-term stability of elasticity at high temperatures.

Product Advantages
1. Scientific material selection based on temperature and stress spectra
We offer tiered material selection based on your precise operating temperature, load type (static/dynamic), and environmental medium. For stable conditions below 500°C, optimized heat-treated A286 stainless steel offers the best value; for oxidizing high temperatures of 600-700°C, Inconel X-750 is the preferred choice due to its superior endurance strength; and for ultra-high temperature scenarios with thermal cycling and complex stress, we recommend Inconel 718 or a custom solution for better resistance to thermal fatigue.
2. Specialized process systems tailored for thermal environments
High-temperature performance depends not only on the materials but also on the manufacturing process. We implement special processes such as vacuum heat treatment and controlled atmosphere quenching to precisely control grain size and the precipitation of strengthening phases, preventing decarburization and oxidation on the material surface. This ensures that the disc spring's performance at high temperatures is highly consistent with the design values, guaranteeing its high-temperature reliability from the manufacturing stage.

Design Support and Customization Value
When your high-temperature system faces the following challenges, generic springs will inevitably fail, and our specialized solutions are the key to success:
•When the operating temperature exceeds 300°C, ordinary spring steel can no longer meet the requirements for long-term stability.
The equipment undergoes frequent hot and cold cycles, causing the elastic elements to break prematurely due to thermal fatigue.
•High load accuracy and repeatability must be maintained even at high temperatures, such as precision high-temperature fixtures or actuators.
We are not only a manufacturer of high-temperature disc springs, but also your engineering partner for tackling thermal challenges. Please provide your operating temperature profile, load spectrum, and environmental details, and our high-temperature materials engineers will provide you with professional analysis and customized solutions.
