V4 powder high speed steel, high speed steel powder Guilin, Yong Wei steel mold 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! By using good programming, circular blade cutter can largely replace ball mills. Small circle runout of the blade and grinding, positive rake angle and light cutting geometry S390 combines high-speed steel powders can also be used for semi-finishing and some finishing processes. The ingredients are by high temperature diffusion homogenization, in some cases also for stress relief. Usually applied to segregation of castings, forgings, castings eliminate casting stress, improve cutting performance. Heated to 150-200 degrees, controlling the heating rate of 100-120 per hour. Heating holding time 2-3min / mm, after the end of the incubation time with the furnace was cooled to 350 degrees Celsius oven. To implement the State Council's "Air Pollution Prevention Action Plan" and the related deployment, vigorously promote public transport and other public services, Beijing, Tianjin and new energy automotive applications, and actively create green public transport system, effectively promote the prevention and control of air pollution in Beijing, Tianjin, and strive to achieve Beijing Tianjin Hebei air pollution control targets for Beijing, Tianjin, Hebei urban agglomerations (Shijiazhuang (including Xinji), Tangshan, Qinhuangdao, Handan, Baoding (including Dingzhou), Xingtai, Langfang, Hengshui, Cangzhou, Chengde, Zhangjiakou) in the bus, etc. public services, the promotion of new energy vehicles, the next two years to promote public transport in Beijing, Tianjin 20,222 new energy vehicles. Processing and heat treatment of high alloy tool steel, low alloy tool steel than is usually more difficult, so the mold manufacturing costs are high speed steel powder, and ASP-23 high speed steel powder its machinability, than the traditional method of producing high Fortunately, alloy tool steel, dimensional stability heat treatment is relatively good, and easy to predict. More because of ASP-23 high hardness, good toughness and high temperature tempering characteristics, especially for surface treatment, very easy to process. Some plastic materials have acid resistance, and some by the addition of a reinforcing agent, or other modifications, such as glass fibers the major damage to the mold, are to be considered during the selection. There is a strong corrosive plastic general election S136,2316,420 a class steel, in addition to the election S136,2316,420 weak corrosive, there SKD61, NAK80, PAK90,718M. Strongly acidic plastic material has: PVC, POM, PBT plastic material has a weak acid: PC, PP, PMMA, PA, single-medium quenching quenching method is the most common, simple operation, equipment, and environmental requirements low. Inadequate water quenching is easily deformed steel, alloy steel water quenching easy to crack. Method of operation is the holding time of the end of the workpiece into some kind of quenching medium DEX20 speed steel powder to the cooling capacity of the cooling medium quenching, cooling conditions this process depends entirely on the cooling characteristics of the workpiece using the medium. Mills use superior resources, weaknesses, the stainless steel products do fine well, despite the current market lower, but many businesses is not overly worried, because excellent product quality, while the current market even approaching low, as long as the resistance maintained, seize the opportunity to make the anti-hunters also a high probability event. National Day, the iron ore spot market transactions are extremely active in cargo turnover is also continuous heavy volume, Dalian iron ore futures even once the daily limit to close at Platts, the highest index also rose $ 83.75 / ton, the highest in nearly a month highs market sentiment continued to pick up. However, iron ore prices really have bottomed out? In fact, this is also related to the late steel to determine the trend, following the author of the latest changes in the market, as we do a brief analysis. Look forward to all of us to grasp the current market situation changes help.
