Mirror-polishable plastic mold steel, pre-hardened to 40 HRC. The vacuum remelting process ensures the highest purity of this steel. It is weldable with the same alloy, and subsequent post-weld heat treatment results in a homogeneous microstructure with uniform hardness without a heat-affected zone.
NAK80 is used for manufacturing plastic molds with large cross-sections and very high requirements for polishing. It has proven particularly effective in molds for headlights, bumpers, dashboards, and generally molds for visually demanding parts. NAK80 is suitable for thermosetting plastics and thermoplastics. Fiber-reinforced plastics usually require a PVD coating.
NAK80 is a trademark product of the Japanese manufacturer Daido Steel. Gebr. Recknagel distributes NAK80 as the exclusive stockholding sales representative for Central Europe.
Save Time and Costs:
Typical Hardness Distribution after Welding NAK80
No hardness differences after welding when subsequently post-weld heat treated.
Cutting Data Recommendations NAK80
NAK80 demonstrates a high thermal conductivity due to its particularly favorable alloy composition, resulting in shorter cooling times.
Notched U-Shaped Test
EDM (Electrical Discharge Machining)
Easily perform fine electrical discharge machining without an increase in hardness of the machined surface.
Hardness reduction and/or distortion may occur with any treatment above 520°C.
