PX88 [] [Hongyuan Hongyuan Hongyuan] [] PX88 PX88 steel mold steel Japan Datong PX88] [Hongyuan Hongyuan] [pre-hardened material PX88 PX88 clinker [] [Hongyuan Hongyuan Hongyuan] [price] PX88 PX88 PX88 heat treatment of materials] [Hongyuan Hongyuan hard material [] [Hongyuan] PX88 PX88 steel rod PX88: PX88 die by the Japan Daido Steel is a pre-hardened plastic mold production of steel, the steel has excellent mechanical properties and workability, widely used in mold processing and production industries. The steel pre-hardened after a special production process, when the factory has had a 30 ~ 33HRC hardness, sufficient to meet the general requirements of the mold hardness of the material, thus reducing the normal mold processing and production of heat-treated areas, enhance economic efficiency . PX88日本大同塑胶模具钢, especially to improve the weldability of common plastic mold steel, P20 improved, hardened and tempered to about HB290-330. In welding crack sensitivity of low alloy composition design, significantly improved welding performance .PX88 steel Japan Datong (DAIDO) special steel, PX5 improved quality steel and pre-hardened plastic mold steel and having a good polishing properties, especially to improve the weldability of common plastic Branch Die steel, widely used in plastic mold. The steel hardness and uniform structure, general pre-hardened steel, weldability, electrical discharge machining, the mirror is good, excellent machinability and polishing performance for EDM. ] Physical properties (hardness specimens 340HBW, at room temperature and high temperature conditions) 1) Temperature 20 ° C / 200 ° C / 400 ° C, a density 7. 8g / cm / 7.75g / cm / 7. 7g / cm. 2) Temperature 20 ~ 200 ° C / 20 ~ 400 ° C, linear expansion coefficient: 12.6 × 10K / 13.5 × 10K. 3) Temperature 20 ° C / 200 ° C / 400 ° C, thermal conductivity 29.0W?
