Schmiedestück

Schmiedestück is the term used in metalworking to refer to a piece of metal that is intended to be forged or has been formed by forging. It can denote either the starting stock for forging, such as an ingot, billet, or preform, or the semi-finished forging itself after initial deformation. The concept underlines the emphasis on forming the material through plastic deformation rather than cutting.

In practice, Schmiedestücke are heated to forging temperature and then shaped by open-die or closed-die forging using hammers or presses. The choice of starting stock geometry and grain-flow orientation aims to produce a part with improved mechanical properties, such as higher strength and toughness, due to the refined, elongated grain structure resulting from deformation. Forge stock selection also considers final geometry, wall thickness, and material volume to minimize waste and post-forging machining.

After forging, Schmiedestücke typically undergo finishing operations, including trimming, machining, heat treatment, and surface finishing, to achieve the exact dimensions and material properties required for the final component. Common applications include automotive and aerospace parts (gears, shafts, connecting rods), powertrain components, and various structural elements that benefit from the strength and reliability of forged metal.

Terminology variations exist; some contexts distinguish between the initial forge stock and the finished forging, while others use Schmiedestück more broadly for the forged part at any stage. Overall, the term emphasizes the role of forging in producing mechanically robust metal components.
