PROPRIETARY Vanadis 6 SuperClean Heat Treatments

  • Soft annealing: Protect the steel and heat through to 900°C. Then cool in the furnace at 10°C per hour to 750°C, then freely in air.
    Stress relieving: After rough machining the tool should be heated through to 650°C, holding time 2 hr. Cool slowly to 500°C, then freely in air.
    Hardening: Pre-heating temperature: Normally two preheating steps 600–650°C and 900–950°C. Austenitizing temperature: 1000–1100°C. Normally 1050°C. Holding time: 30 min. below 1100°C, 15 min. above 1100°C. Protect the tool against decarburization and oxidation during hardening.
    Quenching media: High speed gas/circulating atmosphere; Vacuum (high speed gas with sufficient positive pressure), preferably at least 4–5 bar; Martempering bath or fluidized bed at 500–550°C; Martempering bath or fluidized bed at approx. 200–350°C. Note 1: Temper the tool as soon as its temperature reaches 50–70°C. Note 2: In order to obtain the optimum properties for the tool, the cooling rate should be as fast as is concurrent with acceptable distortion. Note 3: Tools with sections >50 mm (2") should be quenched in sufficient gas pressure and speed. Quenching in still air will result in loss of hardness.
    Tempering: The tempering temperature can be selected according to the hardness required by referencing the tempering graphs on the next page. Temper minimum twice with intermediate cooling to room temperature. The lowest tempering temperature which should be used is 180°C. This temperature should only be used for small and uncomplicated tools. For medium to large size and more complicated tools a temperature of 250°C or higher should be used. When performing a high temperature temper, a temperature to the right of the secondary hardening peak should be chosen. At a hardening temperature of 1100° or higher must be tempered three times (holding time 1 hour) at minimum 525°C in order to reduce the amount of retained austenite. Otherwise the minimum holding time at temperature is 2 hr.
