Durable 4340 Steel Round Bar The First Choice For High Strength Applications - China

4340 steel round bar belongs to alloy structural steel.

Due to its excellent comprehensive performance, it is favored in many high-strength application fields.

It has good hardenability, which means that during the quenching process, a high-strength martensitic structure can be formed relatively evenly from the surface to the inside, thus ensuring the overall mechanical properties of the material.

High-strength performance of 4340 steel round bar

- **Tensile strength**: After proper heat treatment (such as quenching and tempering), the tensile strength of 4340 steel round bar can reach 1000-1200MPa or even higher.

This high-strength characteristic makes it widely used in structural parts that withstand large tensile forces, such as aircraft landing gear components in the aerospace field.

Aircraft landing gear is subject to huge impact and tensile forces during aircraft takeoff and landing.

The landing gear components made of 4340 steel round bars can reliably withstand these loads and ensure the safe takeoff and landing of the aircraft.

- **Yield strength**: Its yield strength can usually reach about 850-1000MPa.

In engineering applications, such as manufacturing the transmission shaft of large ships, the transmission shaft will be subjected to various complex stresses during the power transmission process, including torsional stress and bending stress.

The good yield strength of 4340 steel round bar ensures that the transmission shaft will not easily undergo plastic deformation during operation and maintain stable power transmission.

In summary, 4340 steel round bar has become the preferred material for many high-strength application fields with its high strength and excellent durability, providing a solid foundation for the development of modern industry.
