D2 High Carbon Tool Steel
Steel Properties: Dimensionally stable, high carbon, high-chromium (11%) steel, particularly suitable for air hardening. D2 steel provides superior hardness, high wear-resistance, good toughness, sufficient machinability, and excellent compressive and impact strength.
Application: High-duty cutting tools, blanking and punching tools, wood working tools, shear blades for cutting light-gauge material, thread rolling tools, tools for drawing, deep drawing and cold extrusion, pressing tools for the ceramics and pharmaceutical industries, cold rolls (working rolls) for multiple-roll stands, measuring instruments and gauges, small moulds for the plastics industry where excellent wear resistance is required.
