Detailed Product Description: | Cavity surface of the metal thermal fatigue (cracking). Hot mold work is characterized by intermittent. Each time the thermal state of the metal to be formed after the water cooling of the mold cavity surface of oil, air and other media. As such. Hot mold working condition is repeated heating and cooling, so that the surface of the metal mold cavity to produce repeated thermal expansion and contraction, which repeatedly subjected to tensile and compressive stress. As a result, surface cracks caused by the mold cavity, called thermal fatigue phenomenon, whereby hot die steel is proposed for the second basic performance requirements. That has a high thermal fatigue resistance. Diameter size shoddy steel fluctuations due; L, steel surface temperature instability yin and yang. 2, the composition of the steel uniform. 3, due to poor equipment, low ground strength, source: mold technology mill Colloction big bounce. There will be changes in the larger inner diameter of the same week, so easy to produce steel discontinuity fracture. Heat treatment of high-energy beam source usually refers to the laser, electron beam, ion beam, etc., their common features are: feed material surface power density of at least 103W / cm2, their common features are: fast heating, heating area can be selected M42 steel workpiece deformation is small, does not require a cooling medium, the processing environment clean, controllable, inexpensive to implement automated processing. Heat treatment of high-energy beam principle, process etc invested abroad more research, and improve die life in terms of access to applications. 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 M42 wholesalers, vigorously promote public transport and other public services, Beijing, Tianjin and new energy automotive applications, and actively create green public transport system, effectively promote prevention and control of air pollution in Beijing, Tianjin and M42 , Beijing, Tianjin and air pollution control efforts to achieve the goal for Beijing, Tianjin, Hebei urban agglomerations (Shijiazhuang (including Xinji), Tangshan, Qinhuangdao, Handan, Baoding (including Dingzhou), Xingtai, Langfang, Hengshui, Cangzhou, Chengde, Zhangjiakou ) in the field of public transport and other 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 also higher M42 clinker, 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. Yong Wei mold steel, M42 prices provided by Yong Wei Beibei M42 steel mold.
