Cold working tools
D2 is a high chromium tool steel specifically designed to provide a high abrasive wear resistance and a high hardenability.
It is delivered in annealed condition with hardness below 250 HB. In this condition, D2 has a good machinability.
The grade requires a hardening after machining in order to achieve its service properties. Generally D2 is used with a hardness level within the range 56/62 HRC. The adjustment of the hardness level should be done in order to get the optimum compromise toughness / wear resistance. This grade can be used for cutting and deformation tools submitted to high abrasive wear. It can be used when 2% carbon steels (D3 type) shows an excessive sensivity to cracking or chipping. Main applications are stamping tools, punches and dies, forming dies, shear blades and cutters, ceramic molds, ….
