UNS Forgings and Forged Stock
Last Updated: February 12, 2025
Description
UNS Forgings and Forged Stock are metal components that have been shaped through a forging process. This process involves thermo-mechanically pressing or forging metals and alloys into specific shapes such as bars, rods, or other configurations. The result is a metal part with a dense structure and refined grain morphology, which enhances its strength and durability.
Working Principle
The forging process subjects metal parts to extreme pressures, which refines the grain structure and aligns the grains in the metal microstructure matrix. This is achieved using equipment such as presses and hammers. Unlike casting, forging does not involve melting the metal; instead, it involves striking a rough or preformed shape with a forging hammer or press, causing the material to flow into the desired shape. This process is beneficial because it produces parts with high strength and ductility, making them suitable for critical applications where reliability is paramount.
Applications
Forgings and forged stock are used in a variety of industries and applications. Specific examples include critical component parts in airplanes, automobiles, ships, oil drilling equipment, engines, and missiles. They are also used in the production of mass-produced parts such as screws, rivets, head bolts, and valve lifters. Additionally, seamless rolled rings are used in gear, bearing, and heavy machinery applications.
Advantages over other Forgings and Forged Stock
Forged parts have a continuous grain structure that follows the shape of the part, resulting in stronger products compared to those made through casting or machining. This makes them ideal for mission-critical parts where strength and reliability are more important than cost. The forging process also allows for the production of parts with excellent tensile and yield properties, particularly in applications requiring large and heavy-weight forgings.
Limitations
One of the primary limitations of the forging process is its cost. Production forging is significantly more expensive due to the machinery, tooling, facilities, and skilled personnel required. This makes it less suitable for applications where cost is a major concern. Additionally, the initial setup and design considerations can be complex, requiring careful planning to ensure economical production and reduce die wear.
Considerations
When selecting forgings and forged stock, several factors should be considered. Initial costs can be high due to the need for specialized equipment and skilled labor. Operating expenses may also be significant, particularly in maintaining the equipment and ensuring precision in the forging process. Durability is a key advantage of forged parts, but accuracy in the final product depends on the precision of the forging process and the quality of the dies used. Replacement and maintenance costs should also be factored in, as the wear and tear on dies and equipment can lead to additional expenses over time.
