Forging processes may be opendie, in which simple tools are used whose shape. Since the process is analogous to the way metal has been forged for centuries by. We can create various parts out of a variety of different metals in a range of shapes and sizes. Usually, the metals become stronger and tougher after the forging process due to the modification in its internal grain. The high temperature during hot forging enables the highest possible level of material deformation and the access to complex 3d geometries. In most forgings,the initial grain flow direction longitudinal and the strongest is oriented within the part along.
