Spring steel typically has a high carbon content to further enhance its toughness and strength. During manufacturing, the steel is hardened, giving it both elasticity and wear resistance. The result is a steel that can be bent and return to its original shape multiple times without deforming or breaking. This type of steel is often used in applications where flexibility and durability are essential.
