JFE Steel Corporation | Sheets | Cold-rolled steel sheets

JFE Steel Corporation who holds ISO9001, QS-9000 and ISO14001 certifications, produces a full range of cold rolled products for these and other applications. Because strict quality requirements are now applied to meet the needs of improved product functions, How does cold rolled steel recover ductility?To recover the ductility, cold rolled steels need to undergo an annealing process for the relieving of the stresses that have buildup within the microstructure during the process of cold rolling. Annealing consists of heating of the steel to above the recrystallization temperature, soaking at that temperature and then cooling it.See all results for this questionHot Rolled Steel & Cold Rolled Steel - Difference & Therefore, cold rolled steel is identifiable by an oily and smooth surface. As the working takes place in temperatures below the rescrystallisation temperature, strain hardening occurs. The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel smooth surface cold rolled annealing steel strips for auto c
