Spring steel
Spring steels are intended for components subjected to elastic deformation and cyclic mechanical loading.
Their chemical composition and heat treatment response provide high elastic limits, resilience, fatigue resistance, and controlled hardenability according to the alloying concept.
Individual grades can be tailored for through-hardening capability, impact loading, or elevated stress conditions in demanding service environments.
Typical applications include coil springs, torsion bars, suspension components, retaining elements, agricultural equipment, and other elastically loaded machine parts.
