High Temperature Disc Springs made from Nickel and Cobalt-based alloys are designed to deliver consistent performance in extreme thermal environments—withstanding temperatures up to 700°C and beyond.
These springs provide exceptional fatigue resistance, creep resistance, and oxidation protection, making them ideal for use in power plants, aerospace engines, chemical processing units, and high-pressure valve systems. Materials include Inconel 718, Hastelloy, Waspaloy, and Cobalt-based Haynes alloys, ensuring long life and minimal maintenance even under severe cyclic loading.
