Material cost savings can be significant, whether aluminum, steel or special alloy forging is applied. Rate of scrap and cost-effectiveness of production: Because of the inherent waste to the steel bar and plate machining process, there is always a high rate of scrap and loss in cost.
Metal forming processes Metal forming: Large set of manufacturing processes in which the material is deformed plastically to take the shape of the die geometry. The tools used for such deformation are called die, punch etc. depending on the type of process. Plastic deformation: Stresses beyond yield strength of the workpiece material is required.
Forging produces pieces that are stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, the internal grain deforms to follow the general shape of the part. This results in a grain that is continuous throughout the part, resulting in its high strength characteristics.
Finally, an aging process called precipitation strengthening is done for 24 hours, where it is heated to 250F and then cooled.

After completion of the forging process, the individual workpieces are separated from the bars - usually by means of a hammer blow. Drop forging of bars has both advantages and disadvantages.
Metal bars are sawed or cut to pre-determined lengths and dimensions. The sawed off objects should be free of burrs, as burrs can cause faults in the pressed object. The objects are heated in a gas or induction oven to reach the correct forging temperature. The heating process depends on the dimensions of the object and the choice of materials.
