Tempering Treatment Of High Speed Stamping

Tempering Treatment Of High Speed Stamping

In the High Speed Stamping process, tempering temperature is an important parameter that directly affects the performance and service life of stamping molds or workpiece materials. Tempering is a step in the heat treatment process used to reduce internal stress and brittleness generated during quenching, while improving the toughness and stability of the material.

Here are some key points about tempering temperature in High Speed Stamping:

The purpose of tempering:
Eliminate quenching stress and residual stress to prevent deformation and cracking of molds or workpieces.
Improve the toughness and plasticity of materials, and improve their mechanical processing performance.
Stabilize the size and performance of materials, and improve the service life of molds or workpieces.

Select tempering temperature:
The choice of tempering temperature depends on the type, composition, and required performance of the material. Different materials require different tempering temperatures to achieve optimal mechanical properties.
For materials commonly used in High Speed Stamping molds, such as high-speed steel, alloy steel, etc., the tempering temperature is usually between 400 ° C and 600 ° C. The specific tempering temperature needs to be determined based on the recommended value of the material or through testing.

Tempering time:
In addition to tempering temperature, tempering time is also an important factor affecting material properties. A short tempering time may not be sufficient to completely eliminate quenching stress, while a long tempering time may lead to a decrease in material properties.
The tempering time is usually determined based on the thickness, shape, and required properties of the material.

Cooling after tempering:
The cooling method after tempering can also affect the properties of the material. Common cooling methods include air cooling, oil cooling, and water cooling. Different cooling methods can affect the hardness, toughness, and wear resistance of materials.
