International Mold Steel NAK55 Precipitation Hardened Mold Steel
Categories:	Metal; Ferrous Metal; Tool Steel; Mold Steel
Material Notes:	Description: NAK55 is a precipitation, or age-hardened mold steel with a through hardness of approximately 40 HRc. NAK55 is ideal for use in plastic and rubber molds and other applications where impact resistance is not critical. It is a super clean, Vacuum-Arc Remelted steel with uniform grain structure, uniform hardness and excellent dimensional stability. Unique Characteristics: Vacuum-Arc Remelt manufacturing process. 40 HRc hardness. Uniform 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 50% faster than 30 HRc P20 mold steels. Never needs stress relieving, even after heavy machining.
