Pruduct Description:

Hot rolling involves heating the carbon steel billet or ingot above its recrystallization temperature and passing it through a series of rollers to shape it into the desired bar form. This process enhances the mechanical properties of the steel, such as its strength and toughness.

Cold drawing, on the other hand, involves pulling the carbon steel through a die at room temperature to reduce its diameter and achieve the desired shape. This process can further improve the dimensional accuracy and surface finish of the bar.
