As a benchmark for high carbon and high chromium cold work die steel, D2 steel's core highlight lies in the precise ratio of 12% chromium content and 1.5% carbon to form a large number of hard carbides. It maintains an ultra-high hardness of 60-62HRC while also having better wear resistance than ordinary tool steel (5-8 times that of ordinary steel). After appropriate heat treatment, D2 steel can significantly improve its anti cracking performance, especially suitable for high-strength wear scenarios such as precision punching dies and shear cutting tools. D2 steel, known as "semi stainless steel", also forms a passive film on its surface to delay corrosion, becoming a classic choice for balancing performance and cost in the industrial field.
