Spring steel offers significantly higher elasticity and fatigue strength compared to conventional tool steel. Thanks to its special alloy with elements such as silicon, chromium, and manganese, as well as precise heat treatment, it possesses a high yield strength. This allows the tool to repeatedly return to its original shape, even under high thermal and cyclic mechanical stress, without permanent deformation. This toughness and fatigue resistance result in a longer tool life and extended tool life compared to standard steels.
