Cold working tools
The grade is delivered in annealed condition to keep a good machinability. After machining it requires a hardening to achieve its service properties. The adjustment of hardness should be done to get the best compromise between toughness and 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, etc.
