PROPRIETARY TENAX350 Heat Treatments
- Recommendations to improve tool life: Before starting operation, pre-heat slowly between 250-300°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 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: Preheat tools at 595/650°C and equalize. Continue heating at 815/850°C and equalize. Continue heating to hardening temperature at 990/1030°C. For higher toughness: 1010°C is suggested. Holding time after temperature equalization: 15 to 30 minutes.
Cooling:
a) Oil, hot quenching 500/550°C,
b) Forced air,
c) Vacuum with gas quenching.
Maximum obtainable hardness: 54 + 2 HRC.
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. The first tempering treatment should be performed at least 540°C, and the other treatments between 540-650°C, depending on the desired hardness.
Nitriding: Nitriding must be employed after hardening and tempering, normally in temperatures between 500 and 560°C, since they are at least 50°C lower than the last tempering temperature. As the surface finishing influence the nitriding layer efficiency, it is recommended that the surface is carefully grinned and polished before the nitriding process.
Electro-erosion: When employed in heat treated dies or molds, it is recommended the removal of the altered layer with fine grinding wheel and tempering the die again in a temperature around 50°C lower than that of the last tempering.
