Product Information

AISI 4140 ring forging refers to the process of manufacturing a ring-shaped component using AISI 4140 steel through the forging method. AISI 4140 is a versatile alloy steel known for its high strength, toughness, and wear resistance, making it suitable for a wide range of applications.

The ring forging process typically involves the following steps:

Billet Preparation: A cylindrical piece of AISI 4140 steel, known as a billet, is selected for the forging process. The billet is often preheated to a specific temperature to improve its malleability.

Heating: The billet is heated to a forging temperature, typically between 900°C and 1200°C (1650°F and 2200°F). Heating the steel to this temperature range makes it more ductile and easier to shape.

Forming: The heated billet is placed on a forging press or hammer. Compressive forces are applied to the billet to shape it into a ring. The forming process involves the use of dies that impart the desired ring shape to the material. Multiple forging stages may be required to achieve the final shape, and intermediate reheating may be performed if necessary.

Cooling and Finishing: Once the desired shape is achieved, the forged ring is cooled slowly to relieve internal stresses and improve its strength. Depending on the specific requirements of the application, the ring may undergo additional heat treatment processes, such as normalizing, quenching, and tempering, to further enhance its mechanical properties.



Material: The AISI 4140 ring forging is crafted from premium-quality AISI 4140 alloy steel, which exhibits excellent mechanical properties, including high tensile strength, good hardness, and resistance to fatigue and impact.

Manufacturing Process: The ring forging undergoes a precise forging process that involves heating the material to a specific temperature and shaping it using compressive forces. This process refines the grain structure of the steel, enhancing its strength and durability.
