PROPRIETARY VW9 Heat Treatments
- Recommendations: Preheat slowly between 200 and 300°C before starting the operation. Periodic stress relief throughout the tool life.
Stress relief: The relief procedure should involve slow heating to temperatures between 500 and 600°C and oven cooling to a temperature of 200°C. If applied after work, stress relief must be carried out at a temperature 50°C lower than the temperature of the last temper.
Quenching: The heat for quenching should be between 1100 and 1120°C. It is recommended to pre-warm the tools.
Cool in:
a) Appropriate oil with agitation and heated between 40 and 70°C.
b) Salt bath kept between 500 and 550°C.
Tempering: The tools must be tempered immediately after tempering, as soon as they reach 60°C. Make at least 2 tempers and between each temper the parts must cool slowly to room temperature. Tempering temperatures between 550 and 650ºC, depending on the desired hardness. The time of each tempering must be at least 2 hours. For pieces larger than 70 mm, the time must be calculated as a function of their dimension.
