Resumo
The main aim of this work was to study the behavior of the secondary hardening of AISI
M3:2 high speed steel named Sinter 23® produced by powder metallurgy process of hot isostatic
pressing (HIP). The M3:2 high speed steel Sinter 23® was submitted to heat treatment of hardening
with austenitizing temperatures of 1140 ºC, 1160 ºC, 1180 ºC and 1200 ºC and tempering at 540 ºC,
560 ºC and finally 580 ºC. The effectiveness and response of the heat treatment was determined
using hardness tests (Vickers and Rockwell C hardness) and had its property of secondary hardness
evaluated. The results showed that the secondary hardening peak of Sinter 23® high speed steel
(tempering temperature at which maximum hardness is attained) is at 540 °C for the lower
austenitization temperatures of 1140 °C and 1160 °C, and it is at 560 °C for the higher
austenitizing/quenching temperatures of 1180 °C and 1200°C.
