Improvement of material properties: Through forging, defects such as casting porosity produced during the smelting process of the metal can be eliminated and the microstructure of the organisation can be optimised. Due to the preservation of the complete metal flow, the mechanical properties of forgings are generally reliable to those of castings of the same material.

Improve the internal organisation: forging can make the coarse grain refinement, get dense metal tissue, thus improving the mechanical properties of forgings. At the same time, due to the plastic deformation and recrystallisation of the metal, the coarse grains can be refined to get a dense metal organisation.

Improvement of impact resistance: in the design of parts, if the correct choice of parts of the direction of force and fibre tissue direction, can improve the impact resistance of forgings.

Applicable to important parts: related machinery in the high load, severe working conditions of the important parts, in addition to the shape of the simpler available rolled sheets, profiles or welded parts, generally more forgings.

In summary, the forging process in improving material properties, improve internal organisation, improve impact resistance and applicable to important parts, etc. has obvious advantages.
