Aspect	Hot Rolling	Cold Rolling
Metal Temperature	Above the recrystallization temperature	Below the recrystallization temperature
Work Hardening Effect	Generally does not show work hardening effect	Shows work hardening effect
Coefficient of Friction	Higher coefficient of friction	Comparatively lower coefficient of friction
Experiment Measurements	Difficult to make	Can be carried out easily
Reduction in Area	Heavy reduction possible	Heavy reduction not possible
Mechanical Properties	Improves properties by breaking cast structure and refining grain sizes	Increases tensile strength and yield strength
Rolls Radius	Generally larger in size	Smaller in size
Section Thickness	Very thin sections are not obtained	Thin sections can be obtained
Surface Finish	Metal oxide present, not a good surface finish	Smooth and oxide-free surface
Applicability	Used for ferrous and non-ferrous metals	Applicable to plain and alloy steels, non-ferrous metals, and their alloys
Sequence	Hot rolling is the father of the cold rolling.	Cold rolling follows hot rolling
