By saurabhjain. They both are the metal forming processes. When plastic deformation of metal is carried out at temperature above the recrystallization temperature the process, the process is known as hot working.

Difference between Hot Working and Cold Working

Hot working and cold working are two important and common methods used in metallurgy for the production of a better metal product. These processes are named based on the operating temperatures in which these processes are carried out. The final product obtained from each technique is more or less different from each other. Overview and Key Difference 2. What is Hot Working 3. What is Cold Working 4.

In this article, you are going to learn about the Hot Working and Cold Working process, its advantages and disadvantages in details. If the metalworking process is carried out above its re-crystallization temperature, it is called as hot working. Re-crystallization temperature is the temperature at which atomic mobility can be repaired when any defect was present in the metal caused by the working process. In this process, the metal is heated to the plastic state, and then the pressure is applied to get various size and shapes. If the pressure is applied by hand hammer, then it is called as hand or smith forging. If hand hammering is replaced by power hammers, then it is called hammer forging.

Total Materia New Application Launch! Cold working is the plastic deformation of metals below the recrystallization temperature. In most cases, such cold forming is done at room temperature.

Cold Working Processes

Plastic deformation which is carried out in a temperature region and over a time interval such that the strain hardening is not relieved is called cold work.
