Hot Working vs Cold Working is one of the most important topics in mechanical engineering and manufacturing. In this video, you will clearly understand the difference between hot working and cold working based on temperature, strength, ductility, grain structure, and residual stresses. Hot working is done at high temperature and improves ductility and grain refinement, while cold working is done at room temperature and increases strength due to strain hardening. This concept is widely used in fo
