NAK80 is a premium pre-hardened plastic mold steel known for its excellent machinability, polishability, and uniform hardness. It is specifically designed for high-performance mold making, especially where high surface finish and precision are required. NAK80 is supplied in a pre-hardened condition at approximately 37-43 HRC, eliminating the need for further heat treatment and providing a balance of hardness and toughness.
Key Characteristics:
Composition: Contains nickel, aluminum, and copper, which enhance its hardness, toughness, and corrosion resistance.
Hardness: Pre-hardened to 37-43 HRC, offering a stable hardness ideal for precision mold making.
Machinability: Superior machinability, allowing for efficient cutting and reduced tool wear.
Polishability: Excellent polishability for high-gloss finishes, making it suitable for molds that require a high surface quality.
Texture and Etchability: Good suitability for texturing and etching, which is beneficial for producing molds with specific surface patterns.
Common Applications:
Injection molds for high-precision plastic parts
Molds for electronics, automotive, and consumer goods
Molds requiring detailed texturing or high-gloss finishes
Prototype molds and short-run production molds
NAK80 steel is widely used in the plastic mold industry due to its high hardness, ease of machining, and ability to produce superior surface finishes. It is an ideal choice for manufacturers seeking reliable and high-quality mold materials that perform well under demanding conditions.
