Heating steel billets and forming them in a way that retains or improves the grain structure the material was original drawn with produces a product that is superior in strength and longevity to a casting, fabrication, or machined part. In most cases this leads to a lighter and more efficient package. Forgings also reduce the cost of scrap that is common with machining or other subtractive-manufacturing processes. Forming a near-net shape part to begin with leads to less post-processing.
