Our main imported special steel: Daido, Hitachi : DC53, NAK80, PAK90, PX88, SKS3, H3100, SKD61, SKD11, FDAC, DAC, SLD, SKH-9, S50C Sweden win white: 718, S136, S136H, 8407, DF-2, XW-5 Austria one hundred Paul: M202, M238, M300, W302, K460, K110 Germany Sa Site: 2311,2738,2316,2344,2510,2379 and imports of copper, aluminum, stainless steel, imported high-speed steel, tungsten steel, etc ...... In small molds or workpiece should be sent within two hours tempering treatment HPM50, or vulnerable to cracking quality accident. In order to prevent the finished workpiece surface hardness and wear resistance decarbonization cause reduced HPM50 price, we recommend using a 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 HPM50 manufacturers, softening annealing temperature of 780 holding a certain time (at least 2 hours or more) in a furnace with a cooling rate of not more than 15 per hour After cooling down to 650 to open the door to close 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 HPM50 sheet, stress relief annealing method is the workpiece is heated to 650, soaking for 2-4 hours in the oven After slow cooling to below 350, draws the cooling air.
