Special steel, which possesses specific characteristics and properties, is a type of steel designed and manufactured for various industrial applications. Within this category, there are different tooling grades that have their own unique composition and properties. These grades are specifically engineered to meet the demands of different tooling applications, ensuring optimal performance and durability.
There are several common tooling grades of special steel:
1. High-Speed Steel (HSS): HSS is a type of tool steel that has excellent hardness, wear resistance, and heat resistance. It is ideal for high-speed cutting tools like drills, milling cutters, and taps. Even at elevated temperatures, HSS retains its hardness, allowing it to maintain cutting performance without losing its edge.
2. Hot Work Tool Steel: This type of steel is designed to withstand high temperatures and thermal cycling in applications such as hot forging, die casting, and extrusion. It possesses good toughness, high heat resistance, and excellent wear resistance, which enable it to retain its strength and shape even under extreme thermal conditions.
3. Cold Work Tool Steel: Cold work tool steel is primarily used for cutting and forming applications at lower temperatures. It exhibits high hardness, toughness, and wear resistance, making it suitable for applications like blanking, shearing, and cold forming. Cold work tool steel maintains its hardness even under compressive forces, ensuring long-lasting performance.
4. Plastic Mold Steel: Specifically designed for the production of plastic injection molds and related tooling, this type of steel possesses excellent machinability, high polishability, and good wear resistance. It can withstand the demanding conditions encountered during plastic molding processes, ensuring precise and high-quality molding performance.
5. Powder Metallurgy (PM) Steel: PM steel is a tooling grade manufactured using a powder metallurgy process. This method allows for the production of complex shapes, uniform microstructure, and improved properties. PM steels are commonly used in high-performance cutting tools, wear-resistant parts, and high-strength applications.
These examples represent just a fraction of the different tooling grades available in special steel. Each grade is carefully engineered to meet the specific requirements of various tooling applications, ensuring optimal performance, durability, and efficiency in different industrial sectors.
