May 31, 2020· Cold working is a type of metalworking done by subjecting metal to enough mechanical stress to cause plastic deformation, a permanent change in the metal's crystalline structure. It gets its name because it is done at temperatures below the metal's recrystallization point and alters the metal's structure through mechanical stress rather than heat.

Cold-working The HAYNES® and HASTELLOY® alloys can be readily formed into various configurations by cold-working. Since they are generally stronger, and work harden more rapidly, than the austenitic stainless steels, the application of greater force is normally required to achieve the same amount of cold deformation.

Unlike hot working, cold working causes the crystal grains and inclusions to distort following the flow of the metal; which may cause work hardening and anisotropic material properties. Work hardening makes the metal harder, stiffer, and stronger, but less plastic, and may cause cracks of the piece.

Cold working is the plastic deformation of metals below the recrystallization temperature. In most cases of manufacturing, such cold forming is done at room temperature. Sometimes, however, the working may be done at elevated temperatures that will provide increased ductility and reduced strength, but will be below the recrystallization ...

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 …

verb (used with object) to work (metal) at a temperature below that at which recrystallization occurs.

A common solution is to follow cold working with annealing, or heating the metal to a high-enough temperature to allow grain recrystallization, finding a balance between strength and ductility.
