Automotive leaf springs are produced from low-hardenability and specified hardenability steel, with identical and different length, width and thickness and constant or variable cross section profile, that are subjected to through-surface hardening and low tempering. The ideal critical diameter of hardening, carbon content and hardened layer depth depend on the thickness of constant cross section profile leaf and maximum and minimum thicknesses of variable cross section profile leafs. Adherence to the optimum correlations of parameters indicated make it possible to produce leaf springs with the best mechanical properties and longevity.
