Abstract：This paper deals with the impact of different aluminum content in annealed GCr15 draw steel on the variation of strip texture, microstructure, gain orientation, hardenability n-value, plastic strain ratio r-value and Δr index under the condition of mass production in Hangzhou Iron & Steel Group Co. Experimental results show that within the range of [Al] s=0.017~0.027%, the influence of aluminum on the property of deep-drawing formed GCr15 with high carbon and with low carbon is basically the same. With the increase of aluminum content, the r-value is increased, while the beneficial texture on {111} also go up. However, the r- value of GCr15 steel is much less than that in the low-carbon steel with the same degree of aluminum. While n-value remains more or less the same, Δr index is much smaller, and there is some significant difference in grain orientation. All of these indicate that GCr15 with high carbon has good properties in the above-mentioned aspect, which can meet the requirements of deep forming for common purposes.
