PROPRIETARY VEX Heat Treatments
- Recommendations to improve tool life: Before starting operation, pre-heat slowly between 200-300°C, to obtain thermal homogenization of core and surface. Apply periodic stress relieving during the use of tools.
Stress Relief: Must be employed after machining and before hardening. The stress relief is necessary in dies with draws and profiles, in which the machining removal has been higher than 30%, in other to minimize distortions after hardening. The procedure employs slowly heating to 500-600°C and furnace cooling until 200°C. After tooling, the stress relief must employ a temperature 50°C lower than that of the last tempering.
Hardening: The austenitizing temperature must be between 980 - 1000°C. Cooling:
a) Pressurized vacuum furnace.
b) Oil between 40 - 70°C.
c) Salt bath between 500 - 550°C.
Tempering: Tools must be tempered immediately after hardening, as soon as they reach 60°C. It is necessary, at least, double tempering. After each tempering, tools must be slowly cooled to room temperature. Tempering temperature is between 550 - 620°C. The time of each tempering must be at least 2 hours. For tools larger than 70 mm, the time should be calculated according to their size.
Nitriding: Recommended when higher levels of surface hardness and high abrasion wear resistance are required. It must be employed after hardening and tempering, since the temperature is at least 30°C lower than the last tempering temperature.
