The structures and characteristics of different materials are profoundly altered when the temperature is changed. In this study, rod samples made of AISI 304 medium carbon steel were bored and then hardened and tempered by induction. The goal was to increase the surface layer's hardness. Induction coils are utilised in the process of applying boron paste components to the surfaces of the steel rods. The treated steel rods are put through a series of tests that are designed to analyse both their hardness and their microstructure. In order to evaluate the effectiveness of the treatment on the hardness of the specimens, a total of thirty samples are evaluated using a range of temperatures, dwell times, and feed rates. During the process of tempering, Taguchi optimization is performed in a furnace to optimize the better parameter results for removing internal stresses. This is done so that the stress can be eliminated. The scanning electron microscope (SEM) and the optical microscope are the two types of instruments that are used in the process of analysing materials for both their chemical composition and their microstructure. The formation of martensitic structures has contributed to an increase in the material's hardness values. At temperatures between 800 and 850 degrees Celsius, the values of the material's hardness are lower, while at a temperature of 1208 degrees Celsius, the maximum value of the hardness is 690 HV. According to the results of laboratory tests, an increase in temperature results in an increase in the surface hardness of AISI 304 steel. The results of the comparison show that AISI 304 steel that has been subjected to both boron and induction treatments has a greater hardness value than AISI 304 steel that has only been subjected to induction treatment.
