![Heat-Resistant Disc [X 22 CrMoV 12-1]](https://3antsspring.com/wp-content/uploads/2025/07/b9e3d65844b91f99be2dea37420fce2b.png)
🧾 Product Description:
Our heat-resistant disc spring steels are engineered for extreme performance in high-temperature environments. Withstanding temperatures up to 600°C, these materials—such as H13, 30WCrV17-2, 1.4923, and 1.4122—offer excellent mechanical strength, fatigue resistance, and long-term stability.
Ideal for thermal processing equipment, power generation, aerospace components, and high-pressure sealing systems, these steel grades deliver consistent force and minimal relaxation, even under thermal stress. Thicknesses range from 1.0 mm to 20 mm, tailored to meet diverse industrial specifications.
