Product Description
NAK80 Steel Overview:
NAK80 is a pre-hardened plastic mold steel known for its excellent combination of high hardness, good polishability, and dimensional stability. It belongs to the group of precipitation-hardened mold steels and is commonly used in the manufacturing industry for producing plastic injection molds, die casting molds, and other mold applications requiring high surface finish and dimensional accuracy.
Chemical Composition:
Properties:
1.High Hardness: NAK80 steel is pre-hardened to a high hardness level, providing excellent wear resistance and surface finish in mold applications.
2.Good Polishability: Due to its fine grain structure and chemical composition, NAK80 steel offers good polishability, allowing for the production of molds with high surface finish requirements.
3.Dimensional Stability: The pre-hardened condition of NAK80 steel ensures dimensional stability during machining, heat treatment, and prolonged use, minimizing the risk of deformation or dimensional changes.
4.Excellent Machinability: NAK80 steel exhibits good machinability, enabling ease of machining operations such as milling, drilling, and EDM (Electrical Discharge Machining).
5.Uniform Hardness: The homogeneous microstructure of NAK80 steel ensures uniform hardness distribution throughout the mold, resulting in consistent performance and mold life.
6.High Toughness: Despite its high hardness, NAK80 steel retains good toughness, allowing it to withstand mechanical shock and impact loading without fracturing or chipping.
Applications:
1.Plastic Injection Molds: NAK80 steel is widely used for manufacturing plastic injection molds for producing various plastic components and products.
2.Die Casting Molds: It finds application in the production of die casting molds used for casting metal components with complex shapes and tight tolerances.
3.Blow Molds: NAK80 steel is utilized in the manufacturing of blow molds used for producing hollow plastic products such as bottles, containers, and automotive parts.
4.Extrusion Dies: It is employed in the production of extrusion dies used for forming plastic profiles, pipes, and sheets through extrusion processes.
5.Compression Molds: NAK80 steel finds application in compression molding dies used for forming powdered materials into solid objects under high pressure and temperature.
Heat Treatment:
NAK80 steel is typically supplied in a pre-hardened condition, eliminating the need for conventional heat treatment. However, if further hardening is required, it can be subjected to a secondary hardening process.
Surface Treatment:
Various surface treatments such as nitriding, PVD (Physical Vapor Deposition) coating, and DLC (Diamond-Like Carbon) coating can be applied to enhance the surface hardness, wear resistance, and corrosion resistance of NAK80 steel.
Quality Assurance:
1.Manufacturers of NAK80 steel often adhere to international quality standards such as ISO 9001 to ensure the quality and consistency of their products.
2.Quality control measures include chemical composition analysis, mechanical property testing, and dimensional inspection to meet customer specifications and requirements.
Environmental Considerations:
NAK80 steel is recyclable and can be reclaimed and reused at the end of its service life, contributing to sustainability and environmental responsibility in manufacturing processes.
