- A new cold working die steel was prepared by vacuum arc melting. Its structure characteristics and micro-hardness were measured and investigated. The results indicate that the ingot is mainly composed of dendrites. The grain size increases gradually from the edge to the center along the horizontal direction. Along the longitudinal direction, the structure distributes axial-symmetrically and its evolution characteristics in the upper part differ from that in the lower part. The grain boundary segregates are eutectics composed of ferrite matrix and Cr carbides. Compared with the original Cr12MoV matrix steel, the solidification structure of the composition modified steel is improved, resulting in the lower hardness.
