The main raw materials commonly used in forging are steel, non-ferrous metals and their alloys. Forging raw materials According to the processing state can be divided into ingots and profiles.
Ingot is the original state of the material, after rolling or extrusion and other plastic deformation, you can get a variety of profiles, such as round, square section or periodic variable cross-section of the bar material.
Forgings and some alloy steel, 45# steel plate, special metal forgings forging generally use ingot, through the free forging method to improve its internal tissue state, access to quality of qualified forgings, ingot can also be free forging open billet, forming into a forging billet, according to the size of the use of the original blank.
Most of the small and medium-sized forgings, die forgings using profiles, from the profile to intercept the appropriate length of the material as the forging of the original blank.
