Various industries and applications utilize several distinct molding grades of special steel. Some well-known molding grades are:
1. P20: This grade finds wide usage in the production of plastic injection molds, die casting, and extrusion dies. It boasts excellent machinability, high hardness, and good polishability, making it suitable for high-precision molding operations.
2. H13: Primarily used for die casting and forging applications, this grade is a hot work tool steel. It offers high toughness, good heat resistance, and excellent wear resistance, making it suitable for molding processes in high-temperature environments.
3. S7: Commonly employed in molding applications requiring high impact resistance, this grade is a shock-resistant tool steel. It provides good hardness, toughness, and machinability, making it ideal for applications like shear blades and hammer dies.
4. NAK80: Often utilized for high-quality mirror surface molds and precision molding, this grade is a pre-hardened mold steel. It offers high polishability, excellent dimensional stability, and good wear resistance, making it suitable for producing parts with demanding surface finish requirements.
5. 420SS: This grade, a stainless steel, is commonly used in molding applications that require corrosion resistance. It provides good hardness, moderate strength, and excellent corrosion resistance, making it suitable for applications such as medical devices and food processing equipment.
These examples represent just a fraction of the available molding grades of special steel on the market. Each grade possesses distinct properties and characteristics that render them suitable for various molding applications. It is crucial to select the appropriate grade based on the specific requirements of the molding process to ensure optimal performance and durability.
