Hongyuan Hongyuan [] [] SLD8 SLD8 steel] [Hongyuan SLD8 mold steel Hitachi SLD8] [Hongyuan Hongyuan] [pre-hardened material SLD8 SLD8 clinker [] [Hongyuan Hongyuan Hongyuan] [Price] SLD8 SLD8 heat material] [Hongyuan Hongyuan SLD8 hard materials [] [Hongyuan] SLD8 SLD8 steel rod SLD8 high hardness and high toughness of cold work tool steels, Hitachi high-quality mold steel, SLD8 Hitachi metals is SLD (Japanese standard SLD8) . due to the amount of vanadium added changes workability increased significantly modified version to use this feature, cracking and deformation for time-dependent deformation and wire cutting are suppressed when the Hitachi special steel SLD8 Brand: Hitachi SLD Origin: Japan Day Steel Type: cold steel mold steel two characteristics: SLD8 Hitachi metals is SLD (Japanese standard SLD8) a modified version of the abrasion resistance good general tool steel, hardened and good because the amount of vanadium added to change significantly workability. the rise. SLD better toughness than 50%, while the resistance to temper softening respect to 530 ℃ tempering hardness HRC62-63 can still get in. Take advantage of this feature, for the time-dependent deformation and fracture and deformation of the cutting line are suppressed. Li metal SLD8 better wear a common cold work die steel with good hardening properties, and a small amount of deformation hardening its advantages: 1) the vacuum degassing refining, so the quality is very clean inside 2) Mechanical Good workability 3) hardenability good air cooling can be cured without fear quench cracking 4) heat deformation is very small, very small deviations quenching, most suitable for precision mold 5) wear very best, most suitable for use as stainless steel or high-hard material blanking die 6) good toughness factory state:. HB210 3 Uses: mainly used in precision metal molding or other requirements of precision parts and high wear resistance and toughness of the mold with this steel is easy turning, and should be made sharp knife, scissors, saw, cold or hot trimming mode, simply roll edge, screw pattern, line mode, milling, stamping dies, circular piping, system power transformers heart dies, cutting leather rolled steel knives, steel roll forming Jane, Jane's first roll bars Carpenter, special molding roll simple, precise regulation, shape complexity of the cold tools, metallurgy, tin as mold, plastic mold, mold starts with four screws Chemical Composition (%):.
