Strictly Control 42crmo4 Heat Treatment To Achieve Perfect Combination Performance - China

42crmo4 heat treatment

1 - Quenching

- **Heating temperature**: Heat the steel to 820°C to 880°C (usually 850°C) and keep it for a sufficient time to ensure that the material is fully austenitized.

- **Cooling medium**: Oil or water is usually used as the quenching medium.

Be aware of the risk of deformation and cracking when water quenching.

- **Cooling rate**: Cool quickly after quenching to obtain martensitic structure, thereby improving strength and hardness.

2 - Tempering

- **Tempering temperature**: Tempering is usually between 540°C and 680°C, and the specific temperature is selected according to the required hardness and toughness.

- **Tempering time**: Each tempering should be maintained for at least 60 minutes to ensure uniformity and stability.

- **Purpose**: The purpose of tempering is to reduce the brittleness after quenching and improve toughness while maintaining high strength.

Performance characteristics

After quenching and tempering, 42CrMo4 steel has the following properties:

- **Tensile strength**: can reach 1100-1300 MPa.

- **Yield strength**: ≥930 MPa.

- **Hardness**: usually above HRC 53, depending on the heat treatment conditions.

- **Low temperature impact toughness**: good, suitable for use in low temperature environments.

## **Application areas**

Due to its excellent mechanical properties, 42CrMo4 alloy steel is widely used in:

- Automotive parts (such as gears, bearings)

- Engineering machinery (such as excavators, cranes)

- Oil drilling tools and other mechanical parts with high strength requirements By strictly controlling the heat treatment process, 42CrMo4 can achieve a perfect combination of high strength and toughness, suitable for various industrial applications.
