Cold Work Tool Steels
Cold work tool steels are specialized types of steel designed for high performance in cold forming and cutting processes, providing high hardness, wear resistance, and dimensional stability. These steels typically contain high carbon and alloying elements.
Applications of Cold Work Tool Steels
Cold work tool steels are used in various industrial applications. Key areas of use include:
- Punches: For perforating or shaping metal sheets.
- Molds: For shaping plastics, metals, or other materials.
- Cutting Tools: For cutting, slicing, and shaping operations.
- Blades: For industrial knives and cutting tools.
- Heavy-Duty Equipment: In applications requiring high durability and wear resistance.
These steels are preferred for their ability to withstand tough working conditions and provide long-lasting performance.
Types of Cold Work Tool Steels
- SC 1.2379: Known for high carbon and chromium content, offering excellent wear resistance and hardness. Commonly used in cutting tools, punches, and mold components. Can achieve 60-62 HRC hardness through heat treatment.
- SC 1.2767: Characterized by high nickel content and excellent toughness. Used in mold components, punches, and cutting tools requiring high durability. Can reach 55-60 HRC hardness through heat treatment.
- SC 1.2550: Features high carbon and chromium content, providing good wear resistance and impact toughness. Preferred for cutting tools, molds, and punches. Achieves 58-62 HRC hardness with heat treatment.
- SC 340: A special cold work steel known for high wear resistance and hardness, with high carbon and alloying elements. Used in custom molds, cutting tools, and abrasive parts.
- SC 1.2842: Also known as O1 steel, offering a good balance of hardness and toughness with medium carbon and high manganese content. Used in punches, cutting tools, and molds. Reaches 57-62 HRC hardness through heat treatment.
These steels are specially designed to provide high performance in cold work applications, each optimized for specific hardness, wear resistance, and functionality.
