Plastic mold steel 'NAK55'/'NAK80'
Supports large molds! Excellent in texture processing, electrical discharge machining, and machinability, with good mirror polishing properties due to special melting!
Two types: "NAK55" with excellent machinability and mirror finish, and "NAK80" focusing on high mirror finish. Both are pre-hardened (40HRC) plastic mold steels. They are heat-treated under optimal conditions to achieve 37-43HRC (surface guarantee), allowing for direct use in mold engraving. They have good mirror polishing properties and provide satisfactory gloss. As Ni-Al-Cu based age-hardened steel, they offer good machinability and surface finish. Manufacturer: Daido Steel Co., Ltd. 【Features】 <NAK55> - Suitable for large sizes - Pre-hardened steel that can be processed as is - Good machinability and surface finish - Good mirror polishing properties - Easy to polish after electrical discharge machining - Good weldability <NAK80> - Improved mirror polishing properties, electrical discharge machining surface, and toughness compared to NAK55 - Extremely good mirror polishing properties 【Technical Data】 https://www.daido.co.jp/common/pdf/pages/products/tool/technical-data/sd2302-j03.pdf *For more details, please refer to the PDF document or feel free to contact us.
