The higher the carbon content of steel is, the better the elasticity is, so the spring is made of high carbon steel. Small springs are generally made of high carbon steel in high quality carbon structural steel, such as the damping spring under the bicycle seat, the spring used in the clip, etc.; Medium and large springs are generally made of high carbon alloy steel, such as the shock absorption plate spring of the car with 60Si2Mn, 50CrVA production.
