Application of plastometry technique for hot stamping tool steels

Resumo
This work presents the stress-strain curves using indentation plastometry based on profilometry (PIP) of 1.2367 (X38CrMoV5-3), WP7V, and CP2M® tool steels, after heat treatment in a salt bath, using an austenitizing temperature of 1050 ºC and triple tempering of 2 hours each to attend the hardness range of 54-55 HRC. No significant anisotropy or inhomogeneity was detected in the samples. Samples of CP2M® and 1.2367 steels showed Yield Stress and Ultimate Stress (UTS) values around 1800 and 2000 MPa, respectively, whereas the WP7V steel showed lower Yield Stress of approximately 1750 MPa and a UTS of approximately 2000 MPa.
