Cold working - Wikipedia
Cold working - Wikipedia

Cold working, or ,cold, forming 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.:p.375 ,Cold, forming techniques are usually classified into four major groups: squeezing, bending, drawing, and shearing. They generally have the advantage of being simpler to carry out than hot working techniques. Unlike hot working, ,cold, …

Hot & Cold Working and the Rolling Process
Hot & Cold Working and the Rolling Process

In ,cold rolling,, the metal piece is not heated immediately prior to ,rolling, but the temperature of the workpiece will rise due to the frictional effects of ,rolling,. Steels that are ,cold, rolled become work hardened and annealing is required in order to obtain the desired hardness. The difference between hot rolled and ,cold, rolled steels is the mechanical and chemical properties of the end products.
