Elastic rail clips are typically made from high-elasticity alloy steel or carbon spring steel to ensure they can maintain clamping force under repeated loading without permanent deformation. Common materials include 60Si2Mn, 65Mn, and 50CrVA, which offer high strength, toughness, and excellent fatigue performance, meeting the long-term operational demands of railway and industrial tracks.
