Alloy high-speed steel: SKH-9 Origin, Brand: Japan's Hitachi ● SKH-9 Introduction: SKH-9 high speed steel W-MO Department (6-5-2 type) high speed tool steel, the most universal, especially SKH9 (SKH51 ) in the world, the amount of many instead fine charcoals organizations of W-type high-speed tool steel SKH2, tidy, well-distributed. And homogeneous. So more balanced in terms of wear resistance and leather. Particularly because only the increase or decrease of the carbon content and therefore does not damage the high temperature characteristics, and can be continuous and significantly change the steel nature. The case of low-carbon steels for leather sex, hardness, wear resistance requirements for selection of high carbon steel bell. Rich hot work, cold plasticity, cutting and grinding good ● SKH-9 forging: 1.100 to 900 ° C ● SKH-9 annealing: heating to 800-850 ° C, stay at this temperature for two to four hours, furnace and allowed to cool gradually. ● SKH-9 quenching: first pre-heated to 550-600 ℃, times heated to 950 ° C, and then heated to a: of 1,220 ~~ 1250 ° C; b: 1,200 ℃ to 1230 ℃. Hardened in oil, but the oil temperature must be moisture 40-60 ° C (a. general tools; b. The form of complex needs toughness instruments) ● SKH-9 Tempering: heating to 550-570 ° C, at this temperature stay, and then cooling in still air, the tempering must repeat the second ● SKH-9 Hardness: more than HRC63 ℃ ● SKH-9 Uses: This for tungsten steel high speed steel, suitable manufacturing powerful cutting wear, impact resistance kinds of tools, and advanced die, screw die, than to need toughness and shape complex tools, milling cutters, drills, etc. ● SKH-9 chemical composition: carbon 0.8-0.9 silicon: 0.45 chrome :3.8-4.5 Mn: 0.45 molybdenum 4.5 to 5.5 Vanadium of tungsten 1.6 - 2.2 5.5 - 6.7 Phosphorus: 0.03 sulfur: 0.01 ● SKH-9 factory condition and hardness (surface): HB900-1100/HRC61-HRC63 ● SKH-9 steel general purpose: cutting strength wearable suitable manufacturing senior-heng, mold, screw mold than the required toughness and shape complex tools, milling cutters, drills since its inception has been to quality first, the purpose of the current sales of imported steel, such as high-speed steel. Powder steel high-speed steel. Tungsten steel (alloy steel). Plastic mold steel the metal mold steel steel casting molds. Mirror die steel. Alloy steel, tool steel. Alloy structural steel. Carbon steel. Bearing steel. Imports of copper and aluminum. . . . . . With the full range. The quality and stability. Price. Delivery time and so on.
