Forging
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Forging can produce a piece that is stronger than an equivalent cast or machined part.
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Forging can produce a piece that is stronger than an equivalent cast or machined part. Common forged products are gears, shafts, turbines, automobile parts, railroads, hand tools, kitchenware, jewellery, and etc. Forging is often classified according to the temperature at which it is performed:
Hot forging
Hot forging operates above a metal's recrystallization temperature throughout the whole process. Iron and steel alloys are primarily forged in hot condition.
Cold forging
Cold forging is usually done at room temperature. Brass, bronze, copper, precious metals are manufactured by cold forging processes.
Warm forging
Warm forging occurs between room temperature and a metal's recrystallization temperature. The most common metals that are used in warm forging are steel alloys.
