ASP-23 mold steel material _ _ AsiaVest Heshan ASP-23 provided by the Dongguan City An Yongwei steel mold shop. Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) is specialized in the "mold steel, DC53, SKD11.SUS440C, SUS420" business, the company adhering to the "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Simon / R. DAIDO Datong Steel NAK80 characteristics: (1) mirror polishing performance is very good. ○ 1 due to the special administration of dissolution and refined, so very few impurities. ○ 2 dense tissue. (2) discharge machining performance is very good. ○ 1 because of the machined surface dense and beautiful, it is possible to replace Lipi eclipse flowers. ○ 2 because of the hardness of the machined surface does not rise, so the grinding process faster and easier. (3) welding performance is very good. (4) does not require as heat, direct manufacturing mold. (5) of the original material hardness HRC37-44. Should be sent in small molds or workpiece within two hours tempering Sweden Assab ASP-23, or vulnerable to cracking quality accident. In order to prevent the finished workpiece surface hardness and wear resistance leads to reduced decarburization recommended vacuum furnace heat treatment. Should be used when placing the right amount of resistance heat treatment furnace iron shavings to protect them. DF-2 material in a metal mold to soften the annealing process to improve the cutting performance, and for hardened steel, softening annealing temperature is 780 holding a certain time (at least 2 hours or more) per hour in a furnace cooling rate is reduced to not more than 15 650 after opening the door to cool to near air temperature, after annealing hardness of about 190. DF-2 Mould material during stress relief annealing after rough machining precision molds should stress relief annealed ASP-23, to stress annealing method is the workpiece is heated to 650 ASP-23 material, soaking 2-4 hours, the furnace was slowly cooled to less than 350, draws the cooling air.
