FAQ

NAK80 is a high-performance, pre-hardened plastic mold steel known for its excellent machinability, high hardness, and superior polishability. It is ideal for molds requiring high surface finish and durability.

Hardness: NAK80 has a uniform hardness of approximately HRC 38-42.
Corrosion Resistance: It has good corrosion resistance, making it suitable for use in humid environments or with corrosive plastics.
Polishability: NAK80 can be polished to a mirror-like finish, making it ideal for producing molds with high surface quality.
Wear Resistance: It has good wear resistance, which extends the life of the molds.

Carbon (C): 0.35-0.45%
Silicon (Si): 0.2-0.4%
Manganese (Mn): 0.5-1.0%
Chromium (Cr): 4.5-5.5%
Nickel (Ni): 1.2-1.7%
Vanadium (V): 0.3-0.5%
Molybdenum (Mo): 0.8-1.2%

Plastic Injection Molds: Ideal for high-precision and high-gloss molds.
Rubber Molds: Suitable for molds requiring high surface finish.
Press Dies: Used for manufacturing high-precision parts.
Jigs & Fixtures: Ideal for applications requiring high durability and precision.
Optical Instrument Parts: Suitable for molds used in the production of optical lenses and other high-precision parts.
Medical Devices: Ideal for molds used in the production of medical devices requiring high precision and cleanliness.

Yes, NAK80 can be nitrided to further enhance its surface hardness and wear resistance. It contains 1% aluminum, which responds very well to nitriding.
