In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold work", cutting or grinding a formed object.
Web2 days ago · The average forging temperature necessary for hot forging of different metals is: Up to 1150°C for Steel. 360 to 520°C for Al-Alloys. 700 to 800°C for Cu-Alloys. During hot forging, the billet or bloom is heated either inductively or in a forging furnace or oven to a temperature above the recrystallization point of the metal.
