Resumen
Se presenta un estudio sobre el comportamiento de la microestructura y la dureza del acero 30XГC con temple y revenido bajo en muestras procedentes de diferentes lotes, con el objetivo de determinar la homogeneidad de estas variables en el espesor de cada muestra, así como entre ellas. Aplicando la microscopía óptica y el ensayo de dureza Vickers, se determinó que los lotes de acero 30XГC estudiados no muestran diferencias en cuanto a la dureza y la microestructura en el espesor de
cada muestra, aunque sí se aprecian diferencias entre muestras.
The present study on the behavior of the microstructure and hardness of steel with quenching and tempering 30XГC low in samples from different batches, in order to determine the homogeneity of these variables in the thickness of each sample as well as between them. Using optical microscopy and the Vickers hardness test, it was found that batches studied 30XГC steel show no differences in hardness and microstructure in the thickness of each sample, although differences were seen between samples.
