Abstract

The heat treatment of quenching in carbon steels, is a technological alternative that to increase the mechanical properties due to the microstructural change of material.

 

Actuality, there is no substance for the cooling during the quenching heat treatment of carbon steels, for this reason, the aim of this study is the verification of the mechanical behavior (hardness) and microstructure obtained during hardening of steel AISI 104, using water, coolant radiator and coolant for industrial machining as substance of cooling.

 

The results indicate that the use of coolant radiator favors high hardness in the surface zone (60HRC) and obtaining martensite structure. The use of coolant for machining applications generate lower hardness (52HRC), but favors the presence of bainite in a martensitic matrix leading to the high toughness.
