Product Description 1.DescriptionSpring 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.Back to Top2.ApplicationSpring steel flat bars are widely used on auto fittings, auto manufacturing, hardware tools, chain manufacturing and other machinery manufacturing industry.
