China Special Steel Mould Steel alloy steel

Advanced Speical Plastic Mould Steel Plate with High Strength (NAK80 P21)Steel prehardened karma and high quality mirror plastic die is similar to Japanese Diado NAK80, HSSD NAK80 Steel pre-hardened 38-42 HRC hardness, good and processing performance and polishing performance ,high dimensional accuracy and stability, hardening hardnessElectrode can reach 40 HRC, with the same excellent performance and imported NAK80.Key words: NAK80, P21, B40ApplicationReplace imported mold steel NAK80 are widely used in automobile, computer display screen, camera and mobile phone and other transparent parts and optical components.Characteristic1.Special smelting method ensures that the high purity, even and compact structure, with mirror polishing performance.Washing Equipment 2.Electrical discharge machining performance excellent:Dude to the machining surface smooth, can replace the etching process, and the hardness will not be increased during processing, so the processing efficiency is high3.Good welding processing properties.4.Raw material hardness of 36-45 HRC, no need to heat treatment, can be directly manufacture die.Recommend heat treatmentHeating temperatureºCCooling wayHardness (HRC)Aging temperatureºCHardness (HRC)Preheating temperatureSolution temperatureOil cooling or air cooling30- 35490-55038-42500-600850-910Our services:
