The hardening of steels and ferrous materials is carried out, transforming their ferritic (and pearlitic) microstructure into austenite, raising the temperature, followed by a transformation to martensite (hard), through rapid cooling.

The tempering process using sophisticated high power lasers, associated with state-of-the-art control software, is the process of choice for surface hardening of components, even the most delicate and complex geometry. Thanks to the high control of the thermal input (temperature, energy density, etc.) confined only to the areas to be hardened. In this way, it is possible to treat parts and/or surfaces, which are impossible to harden, using conventional technology and processes, including induction. Furthermore, the precise control of the process makes it possible to efficiently dose the heating and cooling of the zones to be tempered, obtaining higher hardnesses than in conventional processes.
