Abstract

This paper presents a new developed hot stamping die steel with long service life. According to high thermal conductivity and high wear resistance required by hot stamping, the composition and content of alloy elements are scientifically designed by analyzing the influence of each alloy element on the material properties. In composition design, the content of Cr, Mn and Si is reduced, and the content of C, Mo and V is appropriately increased. The optimized heat treatment process is also adopted. After testing, the hardness and cross shock resistance of the die steel have been significantly improved. The service life of the hot stamping die using this steel reaches 530k to 610k strokes.
