ESTUDO COMPARATIVO DE APLICABILIDADE ENTRE OS AÇOS AISI O1 (VND) E AISI D6 (VC 131) ATRAVÉS DE MEDIÇÃO DA DUREZA

Abstract

This class conclusion work studies the comparison of capacity between AISI O1 and AISI D6 steels through the hardness test configuration for use in high performance cutting tools for hard steels. Such an approach is justified by the fact that it is important to analyze comparisons between steels that can reach common characteristics in the fact that this type of adaptation is widely used in general. The purpose of this study is to demonstrate to the reader that through application of processes on steels it is possible to assist in the selection of steels, especially when it is intended to reduce costs, while maintaining the performance of materials. This analysis objective will be through by means of a bibliographic reference survey for theoretical basis, also the application of heat treatments of quenching and tempering in steel samples, so that they gain more hardness that will be measured through a hardness test according to the current norms allowing the analysis. Finally, do a superficial cost survey to corroborate a comparison. After carrying out the described methodology and collecting the data, the study showed that AISI O1 (VND) steel is able to reach hardness as high as AISI D6 (VC 131) and even in a uniform way, being able to replace it perfectly in certain applications even having fewer alloying elements that add other properties. However, due to these elements, the second steel tends to have less wear as reported by the manufacturers, but this also reflects about 20% more in the purchase cost of the VC 131.
