Examples of cold working and hot working
WebHot working is carried out above the re-crystallization temperature and below the melting point. Hence the deformation of metal and recovery take place simultaneously. Cold working is carried out below the re-crystallization temperature. As such, there is no appreciable recovery. Tensile Strength. WebHot working is defined as the plastic deformation of a material at a temperature above its recrystallisation temperature, whereas working below this temperature is called cold …
