Heat the SKD61 tool steel parts to tempering temperature, soak enough time until to Soak thoroughly. The usual tempering temperature range is 400-650°C(752-1202°F), It depend on the tools hardness require and the operating temperature. SKD61 tempering data for your reference as below:
| Temperature [°C] | 400 | 500 | 550 | 600 | 650 |
| Hardness [HRc] | 54 | 56 | 54 | 49 | 47 |
Specific Parameters: The hardness of SKD61 can reach a certain level after proper heat treatment. Its tensile strength and yield strength are also impressive, providing the necessary mechanical strength for demanding applications. The steel has a specific heat capacity and thermal expansion coefficient, which need to be considered during design and manufacturing. Moreover, its hardenability and tempering characteristics play a crucial role in determining its final properties.
In conclusion, SKD61 hot work tool steel is a remarkable material with a well-balanced composition, outstanding properties, and specific parameters that make it an ideal choice for various hot work tooling applications. Its ability to withstand high temperatures, combined with its strength, toughness, and wear resistance, ensures reliable performance and longevity in demanding industrial environments.
