HM NAK80 Tool And Mold Steel Mirror Plastic Die Steel 40HRC
Description: NAK80 is a precipitation or age-hardened mold steel with a uniform through hardness of approximately 40 HRc. It is super clean, Vacuum-Arc Remelted steel with uniform grain structure, uniform hardness, and excellent dimensional stability.Unique Characteristics: Super clean, Vacuum-Arc Remelt manufacturing process.40 HRc hardness.Age-hardened for uniformity of hardness throughout, even in heavy sections.When welded, NAK leaves no witness lines after re-aging.Uniform grain structure with no pin holes, inclusions or hard spots.Machines up to 20% faster than 30 HRc P20 mold steels.Never needs stress relieving, even after heavy machining.Polishes to a superior No. 1 finish, even over welded areas.Applications: Clear lens moldsExtremely critical diamond finish applicationsMolds requiring special EDM finishInformation provided by International Mold Steel.
