C75S steel is a high-carbon spring steel known for its good elasticity and tensile strength. The “S” in its designation indicates it is of a special quality, often with stricter controls on impurities like sulfur and phosphorus. The key C75S properties of high hardness and flexibility are developed through quenching and tempering.
This C75S material is a reliable choice for springs that require good durability and formability, making it widely used for components like automotive springs, clips, washers, and various industrial blades.
