Used for long run tooling application where wear resistance is important, such as blanking or forming dies and thread rolling rolls and thread rolling dies, cold extrusion tools, woodworking, cutting and stamping tools for sheet thicknesses up to 6mm, precision cutting tools up to 12 mm. Cold pilger mandrels, circular-shear blades, deep-drawing tools. Pressure pads and highly resistant plastic moulds. Toughness better than D3.possibility of nitriding. |
