In order to make the general performance of cold-rolled sheet 08A1 from GB710-65 standards, improve the quality and performance standards to GB5213-85 deep red car plates, its chemical components were selected (low manganese carbon), and select the appropriate reduction rate (50 to 55%); improve the final annealing temperature (maximum temperature increase than the original 10 ℃); choose the right flat reduction, elongation control at 0.8 to 1.2 percent. Finally, so that the average performance of cold-rolled sheet 08A1 achieve standards of quality and performance GB5213-85 deep red car panels, has received considerable economic |
