Optimizing Heat Treatment Scm440 Steel Get The Desired Features - China

The heat treatment process of SCM440 steel usually includes the following steps:

1 - **Annealing**: SCM440 steel is heated to an appropriate temperature (usually about 800-850°C) and then cooled at a controlled rate to reduce internal stress and improve processing performance.

2 - **Normalizing**: The steel is heated to slightly above its critical temperature (about 870-900°C) and then cooled in air.

This can improve the toughness and impact resistance of the steel.

3 - **Quenching**: The SCM440 steel heated to a high temperature is quickly cooled into a medium (such as water, oil or gas) to achieve the highest hardness and strength.

The usual quenching temperature range is 840-870°C.

4 - **Tempering**: After quenching, the SCM440 steel is heated to a lower temperature (usually between 150-600°C) and maintained for a certain period of time to adjust its hardness and strength while reducing brittleness.

These heat treatment steps can be adjusted and optimized according to specific workpiece requirements and application scenarios to achieve the best mechanical properties and durability.
