Product Description:
Spring steel refers to steel due to the elasticity in the quenched and tempered condition, and specifically for the manufacture of springs and elastic components. Spring steel depends on its ability to elastically deform, i.e., within the prescribed range, the ability to withstand a certain elastic deformation so that the load does not occur in the permanent deformation after the load is removed.Spring Steel is typically used because of its' high yield strengths, resistance to deformation and its ability to return to its original shape.
Application:
Automobile plate spring
