Effect of the solidification structure on the ridging and drawability of ultra low carbon ferritic stainless steel

TF7; In order to understand the effect of the solidification structure on the formability of ultra low carbon ferritic stainless steel (FSS),this work studies the ridging phenomenon and the deep-drawing property in detail and the research method was X-ray diffraction (XRD) and scanning electron microscope (SEM) technique.The result shows that the columnar grain specimen had a higher ridging height than the equiaxed grain specimen,which was mainly attributed to the formation of grain colonies in the columnar grain specimen.After final recrystallization annealing,the equiaxed grain specimen obtained a high-intensity γ-fiber texture and an excellent deep-drawing property.
