Product Description Plastic Mould P80ESR Special Steel (NAK80), Plastic Mould P80ESR Special Steel (NAK80) Standard and Grade: GB NAK80ESR JIS NAK80 Size: Round Bar: Φ 20~300mm Flat: 20~90*205~405mm Mould: 100~500*500~1000mm Chemical composition: C Si Mn Ni Al 0.12 0.35 1.80 3.20 1.0 Delivery condition: Pre-hardened: 37-43HRC Applications Used for high-grade mirror mold, e. G. Molds for transparent products like cosmetics containers, food containers and daily electrical appliance; Used for the mold focusing on discharge machining surface, e. G. Molds for such products as fruit plate, food box, computer casing, keyboards and automobile interior decorations. Used for plastic molds under long production at high precision, e. G. Molds for such products as electrical switches, multifunctional sockets, plugs, charger casing and computer parts. Characteristics Very good workability and mirror polishing property, suitable for thermoset molding of general resin; P80R is a steel smelted by using refining degassing and ESP remelting, suitable for super-mirror molds with high polishing property requirements; The polishing property and workability are the best among the plastic mold steels; Supplied in pre-hardened state, suitable for direct mold cutting without heat treatment; After electric spark machining, the surface hardness is not increased, so that it is easy to repair and Polish the mold.
