SKS3 manufacturers, Yong Wei steel mold (certified), Liuzhou SKS3 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. But overall, the current Zhongshan mold steel market still lags behind the needs of mold industrial development. According mold experts, a considerable part of the requirements of high mold steel need to go through the vacuum refining and remelting to ensure high purity steel, high density, higher anisotropy, of which more than general quality mold steel, high-quality less steel mold, and mold steel by remelting share is small. Zhongshan die steel market is about 80 percent black round bar, at present, alloy tool steel production in China has been ranked the world SKS3 steel, alloy tool steel which is about 100,000 tons. For eutectoid steel and steel castings and forgings hypereutectoid, or tools, dies, ball bearing steel pearlite, carbide ball, refine the organization, eliminate stress, reduce hardness, improved ductility, toughness. Heated to 20-30 degrees Celsius above Ac1 annealing, Ac1 20-30 degrees Celsius above the ball. Heating holding time and fully annealed same. Upon cooling SKS3, hourly rate cooled to 20-30 degrees Celsius temperature ball, the ball after furnace cooling to 450-500 degrees Celsius baked. With the rise SKS3 various domestic manufacturers yearly operating costs, steel infrastructure ideas also tend to go out, Southeast Asia, such as Indonesia, Myanmar, Vietnam is becoming a popular investment treasure. Indonesia, which is due to make policies to attract a large number of domestic manufacturers to invest settled, but factors such as political instability in Indonesia this year, firmly implement the ban on mining, investors wait and see situation in subsequent indecisive, the actual start start building or less. Temper brittleness can be divided into first class and second class temper brittleness temper brittleness. The first category, also known as irreversible temper brittleness temper brittleness, mainly in the tempering temperature is 250 ~ 400 ℃ when SKS3 rod, brittle disappear after reheating repeated in this interval temper brittleness no longer occurs, the second Also known as reversible temper brittleness temper brittleness temperature occurring in the 400 ~ 650 ℃, when reheated brittleness disappears, should be quickly cooled, can not stay long or slow cooling in the range of 400 ~ 650 ℃, otherwise it will happen again catalyzed phenomenon. The occurrence of temper brittleness of steel alloying elements contained in the relevant, such as manganese, chromium, silicon, nickel produces tendency to temper brittleness, and molybdenum, tungsten has a tendency to temper brittleness and weakening. Die steel, such as 3Cr2W8V, H13,5CrNiMo, 5CrMnMo etc., using higher than conventional heating quenching quenching temperature, can reduce the number of carbides in the steel to improve its morphology and distribution, so that the solid solution of carbon in austenite distribution technology, after quenching can get more lath martensite in the steel to improve its fracture toughness and thermal fatigue resistance, thus prolonging the life of mold. For example, one hot 3Cr2W8V steel extrusion dies, conventional quenching temperature is 1080 ~ 1120 ℃, tempering temperature is 560 ~ 580 ℃. As we all know, this year the real estate market is very weak, the price of a continuous downward, closing the sluggish performance of the economy as a whole form a larger pressure, to a certain extent, restrict the continued development of the economy. Then, after the country have relaxed the restriction, the central bank introduced the New Deal in the end of September: the lower the lending rate is 0.7 times the benchmark lending rate, to have two sets and more housing and home loans have been settled respective families, and apply for loans to buy housing banking financial institutions should carefully grasp according to the borrower solvency, credit conditions and other factors and to specify the down payment ratio and lending rates
