NAK80

NAK80 plastic mold steel is a Ni-Ni Al-Cu precipitation age-hardening steel with high polishability. Daido NAK80 plastic mold steel by adding sulfur to make the steel has good workability, mirror machinability and electrical discharge machinability, has good weldability, in the welding part of the hardness of the first decline, after welding by 500 ° C × 5 hours of aging treatment and air cooling, its hardness and heat-affected zone hardness and the hardness of the same as the base material. After gas nitrocarburizing, the hardness of the surface layer reaches 750HV, which can improve the service life.NAK80 plastic mold steel is produced by special melting, which has the advantages of high purity, high stability, excellent machinability, easy to replenish the weld, uniform hardness, good polished, good finish, easy to grind after discharge machining, easy to surface nibble and long service life, and other excellent characteristics. In addition, Daido NAK80 prehardened plastic mold steel does not require any heat treatment, as well as good polishability and etching performance. May have a relationship with the sulfur content, in general NAK80 plastic mold steel shall not directly do EDM skin pattern.

Japan Tatung NAK80 plastic mold steel is widely used in transparent products plastic molds, optical electronic product molds, electro-etching molds requiring good surface finish, long-term production of high-hardness precision molds, mirror polishing molds, TV filters, cosmetic boxes, moving mold inserts and other mold steel above.

NAK80 is the improved material of NAK55 mold steel (mirror polishing, EDM, toughness), in addition to all the characteristics of NAK55, it also has excellent mirror polishing, EDM surface is exquisite and beautiful, and can replace the pear skin etching pattern. NAK80 is used in applications that emphasize transparency and mirror polishability.
