International Mold Steel NAK80 Precipitation Hardened Mold Steel
Categories:	Metal; Ferrous Metal; Tool Steel; Mold Steel
Material Notes:	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 molds Extremely critical diamond finish applications Molds requiring special EDM finish Information provided by International Mold Steel.
