4) Mechanical Properties - Mechanical Property
1. Pre-heat treatment The H13 steel steel and die blank supplied on the market have been annealed heat treatment in the steel mill to ensure good metallographic structure, appropriate hardness, good processability, and no need for annealing. However, after the manufacturer carried out the forging, the original structure and properties were destroyed, which increased the forging stress, and had to be reannealed.
The isothermal spheroidization annealing process is: 860~890 °C heating and insulation for 2h, cooling to 740~760 °C isothermal 4h, furnace cooling to about 500 °C out of the oven.
2. Quenching and tempering Mold quenching process specifications requiring good toughness: heating temperature 1020~1050 °C, oil cooling or air cooling, hardness 54~58HRC; It requires hot hardness based mold quenching process specifications, heating temperature 1050~1080 °C, oil cooling, hardness 56~58HRC.
Recommended tempering temperature: 530~560°C, hardness 48~52HRC; Tempering temperature 560~580°C; Hardness 47~49HRC.
Tempering should be performed twice. When tempering at 500 °C, the tempering secondary hardening peak occurs, and the tempering hardness is the highest, the peak is about 55HRC, but the toughness is the worst. Therefore, the tempering process should avoid about 500 °C. According to the use of mold, tempering is better in the range of 540~620 °C.
Quenching heating should be preheated twice (600~650 °C, 800~850 °C) to reduce the thermal stress generated by the heating process.
3. Chemical heat treatment H13 steel can further strengthen the mold if it is gas nitriding or nitrocarburizing, but its nitriding temperature should not be higher than the tempering temperature to ensure that the core strength is not reduced, thereby improving the service life of the mold.
