Quality Assurance Aisi 5120h Steel Manufacturing Automotive Gears Best Material - China

AISI 5120H steel is a low-carbon alloy carburizing steel.

It has become one of the preferred materials for automotive gears due to its excellent comprehensive performance.

The following is its core advantages and application analysis as a gear material: Heat treatment adaptability:

- **Carburizing and quenching**: aisi 5120H steel surface hardness can reach HRC 58-62 (wear resistance), and the core maintains HRC 30-45 (impact resistance).

- **Controllable deformation**: Suitable for precision gear processing, reducing the cost of correction after heat treatment.

- **Mechanical properties of aisi 5120H steel**:

- High fatigue strength (especially contact fatigue), suitable for gear working conditions with high frequency loads.

- Good bending strength to avoid the risk of tooth root fracture.

Automobile gear application scenarios**

Typical parts: medium and high load parts such as gearbox gears, differential gears, and drive shaft gears.

- **Comparison with other materials**:

- Lower cost than 20CrMnTi (reduced Ni/Mo content), but similar performance.

- More impact-resistant than medium carbon steel (such as 45 steel), suitable for dynamic loads.

Conclusion

aisi 5120H steel is an automotive gear material with a balance of economy and performance, especially suitable for medium and high loads and mass production scenarios.

It needs to be optimized in combination with specific working conditions and heat treatment processes.
