Chrome Silicon Compression Spring for High Temperature Environments up to 200°C
Our chrome silicon alloy compression springs are engineered specifically for high-temperature applications, maintaining reliable performance at continuous operating temperatures of 200°C with minimal force loss. Ideal for demanding environments including heat guns, coffee machines, and industrial ovens.
Product Overview
Standard music wire springs experience significant relaxation above 120°C. Our chrome silicon compression springs overcome this limitation, operating continuously at 200°C while maintaining force integrity. Available with custom wire diameter, outer diameter, and spring rate configurations.
Technical Advantages
Heat causes standard stainless or music wire to undergo stress relaxation, leading to gradual force decrease and potential valve leakage or poor contact. Chrome silicon alloys (SAE 9254) maintain excellent anti-relaxation performance at elevated temperatures, making them the preferred choice for automotive engine valve springs and turbocharger wastegate actuators.
Tingfeng Hardware utilizes chrome silicon wire with precisely controlled heat treatment processes, employing higher tempering temperatures than conventional methods to further stabilize the microstructure. We provide calculated recommendations for optimal initial stress levels based on your specific operating temperature (100-200°C) and required service life, ensuring force degradation remains within acceptable limits throughout your product's lifetime.
