  Forging is a processing method that uses forging machinery to pressure the metal blanks, which obtains certain mechanical properties, certain shape and size of forgings by the plastic deformation of the metal blanks. It is also one of the two major components of forging (forging and stamping). Forging can eliminate defects like loose as cast condition that produced in the smelting process of metal and optimize the microstructure. At the same time, the mechanical properties of forgings are generally better than the same material castings because of the preservation of a complete metal flow line. Most of the important parts with high load and severe working conditions in the related machinery use forgings except some simple shape parts can use rolling plate, profiles or welding parts.   Deformation temperature   The starting recrystallization temperature of steel is about 727 ℃. However, 800℃ is widely used as the dividing line: the hot forging is higher than 800 ℃; the f...
