In the contemporary scenario, much has been discussed about the role that Non-Destructive Testing (END) plays in current industries. One can highlight the ultrasound, being the method that allows the evaluation and inspection of a given material or product without hindering its further use. Thus, the present work seeks to predict the behavior of mechanical properties such as yield strength, tensile strength, and elongation with respect to the velocity of the shear ultrasonic wave, and also allows comparison of how such properties behave in material subjected to heat treatment of Normalizing, Quenching, Quenching followed by Tempering, and Full Annealing. Since in the manufacturing process the use of destructive mechanical tests is recurrent, the need to reduce material waste is high. Thus, as main results, it was possible to verify that for the materials without heat treatment the yield and strength limits estimated presented a standard deviation of maximum, ±4.7 and ±5.2 MPa, respectively. It is possible to state that the non-destructive inspection method can be used to ensure that the mechanical characteristics are in accordance with those specified by ASTM A131/131M. It was also found that the technique is not applicable to predict the separation of materials with different microstructures, being necessary to analyze a larger amount of samples for this purpose.
