Yong Wei _QRO-90 mold steel rod _ Beibei QRO-90 provided by the Dongguan City An Yongwei steel mold shop. Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) is a professional "mold steel, DC53, SKD11.SUS440C, SUS420" of the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to healthy competition in the market, so that "Sweden Assab, Daido, Hitachi, Austria Bluff" brand has a good reputation. We adhere to the "service first, customers first" principle, the permanent mold steel Granville won the trust of customers congregation in special steel, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! 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 in the world, of which about 100,000 tons alloy tool steel. 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. When cooled to 20-30 degrees Celsius per hour speed of the ball is cooled to a temperature, the ball after cooling to 450-500 degrees Celsius oven baked. With the rise year by year QRO-90 sheet of the operating costs of the domestic mills 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. Mold steel manufacturing is the basis for the entire industrial manufacturing technology and equipment, electronics, automotive, electrical, electronics, instrumentation, home appliances and telecommunications products, 80% to 90% of the parts have to rely mold forming, determines the shape of the mold of these products shape QRO-90, processing quality and precision mold will determine the quality of these products. The future of China's mold industry after restructuring, precision molds will be higher QRO-90 manufacturers, mold steel requirements are also increasing. For a quenching medium cooling during the quenching operation. Mainly used in high, medium carbon steel parts, in order to ensure adequate hardened layer to prevent quenching crack. A process used to reduce the deformation. Commonly used in the water - oil, water - air, oil - air and other media. Slightly removed from the workpiece furnace stay a while quenching into water "cold be quenched" in the air also belongs dual media quenching. From this point of view QRO-90 wholesalers, on the one hand, this winter seems to be earlier than in previous years, even holding similar to last year's operating margin rate of decline in the raw material market pressures to be overlooked; on the other hand, as of October In early focus mills up to 15.689 million tons of steel inventories remain higher than normal inventory level was nearly three million tons, 2.189 million tons Yijiao same period last year, with the winter of neighboring companies to the stock return of funds will increase demand In this process may also take the initiative to cut production in order to reduce pressure on the stock of finished products. Taking into account the cuts during the APEC meeting in early November, Hebei and other places likely to face a decree, if the supply is gradually reduced expectations are confirmed, then the pressure on the raw materials market will be significantly higher.
