Earlier, blacksmith uses hammer and anvil to execute the forging process. The smithy has developed over centuries to become a facility with engineered operations, production equipment, tooling, raw materials and products to attain the demands of modern industry. Now-a-days, industrial forging is done either with presses or with hammers powered by compressed electricity, air, hydraulics etc. Small power hammers around 500 lb (230 kg) or less reciprocating weight, and hydraulic presses are usual in art smithies as well. Steam hammers, instead of being in use sometimes became obsolete with handiness of others. Some metals might be cold forged, but iron and steel are always hot forged. Work hardening is prevented by Hot forged that would result from Cold forging, this would increase the difficulty level of performing secondary machining actions on the piece. Metals that is tractable to precipitation hardening, such as most aluminum metals and titanium, could be hot forged, followed by hardening. Significant capital expenses for machinery, tooling, facilities and personnel are being involved in Production forging. In hot forging, a high-temperature forge is needed to heat ingots or billets. In the case of drop forging operations, provisions must be made to take over the shock and vibration that is being generated by the hammer. Most forging processes use metal-forming dies, which must be precisely machined and carefully heat-treated to correctly shape the work piece, as well as to withstand the remarkable forces involved. Corgings in carbon steel or steel whose major alloying element, carbon, produces the resultant properties and hardness. The four main types of carbon steel are low carbon steel, medium carbon steel, high carbon steel, and very high carbon steel. It depends upon the amount of carbon present in the material that whether carbon steel forgings are hardenable by heat treatment to increase yield and impact potency as well as wear resistance. Mild carbon steel carries 0.05% to 0.26% carbon and encompasses grades 1018 and 1020. The lower carbon substance causes the material to be more flexible and less fragile, making mild carbon steel an excellent choice forging. Medium carbon steel carries 0.29% to 0.54% carbon and includes steel grades 1141. Medium carbon steel could be used in the quenched or tempered structure for forged crankshafts and many other types of forgings with having a higher level of manganese, High carbon steel and very high carbon steel demonstrates hardness as well as resiliency and are brittle due to their higher carbon stuffing, between 0.55% and 2.1%. Cold forging is conducted at or near ambient temperatures to generate metal components to close tolerances and grid shape. For example cold drawing, bending, punching, cold heading, coining extrusion, thread rolling and others. Impression die forging or true closed die forging are being involved in cold forging with lubricant and circular dies at or near room temperature. Most commonly cold-forged are Carbon and standard alloy steel forgings. Parts are commonly proportioned and seldom exceed 25 lb. The primary advantage is the material savings achieved through precision shapes that require little finishing. Entirely contained impressions and extrusion-type metal flow yield draft less, close-tolerance components. Production rates are very high with exceptional die life. While cold forging generally improves the mechanical characteristics, the enhancement is not useful in many common forging applications and economic advantages stay behind the prime concern. Tool designing and manufacturing are important.
