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 combined can also be used for semi-finishing and some of the finishing process. 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 SUS420J2, 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 and 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 SUS420J2 rods and other public services to promote new energy vehicles in 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 higher, while the ASP-23 high speed steel powder its machinability, manufacture than traditional methods of high-alloy tool steel Fortunately, 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. China at this stage is still in the demographic dividend period, there is a lot of labor, lower labor costs relative to developed countries; market, the mold industry, the Ministry of steady advances in traditional markets and actively open up emerging markets, even in the past ignored edge of the market has also been development, which are for the mold industry to develop a broad market space; In recent years, the Chinese government has issued a series of policies to support the casting, the development of domestic metal casting industry, but also to create a good development space for the mold industry. Shoddy die steel prone to folding. Folding is formed on the surface of a variety of die steel fold, this defect often throughout the product's portrait. The reason is due to shoddy manufacturers of folding the pursuit of high efficiency, reduction is too large, resulting in the ears, it creates a rolling when folded down, the product will crack when folded bend, making the strength of the mold steel declined significantly. October is the best month SUS420J2 infrastructure projects in construction materials, but also years of outdoor construction remaining good "days"; in infrastructure in order to complete the annual task of pressure, I think, this time next month or so, is outdoor season SUS420J2 steel construction of infrastructure projects, under the rush period, driven by demand for steel and other construction Xianluo should also release a more centralized point. The September manufacturing PMI index is relatively stable, indicating that the domestic economy is stable, but lower portion of the index also reflects the economic side there is still downward pressure in the future. At the same time, good bad macro intertwined; relax or stimulate the property market, real estate credit market confidence, but it is difficult to form a clear effect in the short term.
