The steel has a wide range of applications in the industry, being of extreme importance in any manufacturing process. The SAE 4320 steel is used in a lot of ways, some of them are the transmission systems like gears and pinions. The heat treatments are used to improve some properties of the steel-like, hardness, ductility, and impact resistance. There are many different types of heat treatment. In this article, it was made the tempering process in water and oil, and the quenched process was done in the samples. The purpose of this activity is to do the heat treatments, that were mentioned before, in the SAE 4320 steel, and then analyze with tests the mechanical property variation in the shear force during the machining, with the objective of verifying if there is any correlation between these parameters and if the shear force is also influenced by this modification of the microstructure. Some parameters, like the time that the sample was in the austenitization temperature and the machining, parameters were fixed. After the heating treatments, some analysis of the microstructures and hardening were made.
