Tempering is carried out to relieve stresses from the hardening process, but primarily to obtain mechanical properties required for the final application. The actual tempering temperature will be chosen to meet the required properties, and in many cases will be a matter of trial and error.This grade SAE 4340 steel coil may also be hardened by nitriding or flame or induction hardening.SAE 4340 steel coil is readily machinable, with either a coarse lamellar pearlitic structure or a SPHEroidized structure being best advised, depending upon section size and complexity and amount of machining to be carried out. If there is doubt about the suitability of any other structure, then a spheroidizrd structure should be aimed
