Forging workpiece products Compared with castings, metal can improve its structure and mechanical properties after forging. Due to the deformation and recrystallization of the metal after the casting structure is thermally processed and deformed by forging, the original coarse dendrites and columnar grains become an equiaxed recrystallization structure with finer grains and uniform size, so that the original segregation, The compaction and welding of porosity, pores, slag inclusions, etc. will make the structure more compact and improve the plasticity and mechanical properties of the metal.

The mechanical properties of castings are lower than those of Forging workpiece products of the same material. In addition, the forging process can ensure the continuity of the metal fiber structure, so that the fiber structure of the Forging workpiece products is consistent with the shape of the Forging workpiece products, and the metal streamlines are complete, which can ensure that the parts have good mechanical properties and long service life. Precision die forging Forging workpiece products produced by , cold extrusion, warm extrusion and other processes are incomparable to castings.
