Abstract
The steel sheet are the most materials used in building structures and machines because it cheap and extensively. The influences of cold and hot roll drawing processes on the main mechanical properties, microstructure and corrosion rate are different. During both types of drawing the material is subjected to very high pressing under both low and high recrystalaization temperature. In this present work the effects of cold and hot roll drawing on the tensile strength, hardness, microstructure and corrosion rate for steel sheets were discussed. In the experimental work we used different thickness specimens taken from low carbon steel sheets formed by cold and hot roll drawing in Libyan Iron and steel Company- Musrata City. The experimental results indicate the specimens under testing subjected to change in main mechanical properties during thickness reduction in rolling operation. The cold and hot roll drawing causes changes in microstructure due to plastic deformation and temperature effects. Also the influence of cold roll drawing on tensile strength, hardness and corrosion rate were found to be increasing while the ductility will be decreased. In hot roll drawing the tensile strength and hardness will be decreased due to high temperature while the ductility and corrosion rate increased.
