Zengcheng SKD62, Yong Wei mold steel, SKD62 material 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! Shoddy material surface is easy to crack because it is blank adobe, adobe many pores, adobe in the process due to the cooling effect of the thermal stress cracks SKD62 suppliers, there is a crack after the rolling. No shoddy steel metallic luster, pale red color of pig iron or similar reasons two two, it's blank is adobe. 2, shoddy-rolling temperature is not standard, they are visually steel temperature, so that the region can not be defined by the austenite rolling SKD62, the natural properties of the steel can not be reached. Important uses for steel and alloys, sometimes using more than twice tempered. For tool steel, tool steel, steel casting molds, stamping die steel, hot die steel, cold work die steel, tool steel and high carbon cars than the steel can be processed using this technology. To a certain extent increase the hardness level of SKD62 appropriate mold, to improve the dimensional stability, and further to eliminate the residual austenite to eliminate thermal stress and stresses caused by the previous tempering. For high-speed steel is often carried out three times or more tempered. Iron ore price downturn, the supply of iron ore to China had a profound impact. Direct impact on the domestic mining began large-scale production. With the high cost mines are gradually out of the market, the end of September of iron ore fines mine capacity utilization rate 61.8%, dropped 17 percentage points over the beginning of high cost of iron ore mining, most of mine at a depth of about 300 m the survey showed that iron ore production costs Shanxi, Liaoning region (not included) Mainstream between $ 90-110. In addition SKD62 rod, iron ore companies also bear certain taxes, in 2014 a quarter of China's Steel Association announced iron ore mine average rate of corporate tax burden was 21%, up to 30%, and 20 tax items number. The use of the workpiece is heated to a higher temperature and a longer time for the aging treatment aging treatment process, known as artificial aging treatment, when the workpiece is placed at the natural conditions or prolonged storage at room temperature aging phenomenon occurs is called the natural aging treatment. The purpose of the aging process, eliminate the internal stress of the workpiece, stable organization and size, to improve the mechanical properties. The source of high energy beam heat treatment usually refers laser, electron beam, ion beam or the like. Their common features are: supply of steel mold surface power density of at least 103W / cm 2. Their common features are: fast heating, heating area can be selected according to the needs of small deformation of the workpiece, does not require a cooling medium, the processing environment clean, good controllability, easy to implement automated processing. At home and abroad on the principle of high-energy beam of heat treatment, process etc to invest more research, more mature laser transformation hardening, small and medium-power electron beam treatment of ion implantation and improve die life gained a level applications . From the trend of the domestic steel price index situation, late June, the trend began long products price index was weaker than plate price index. The continuation of this trend in the third quarter, and the weak trend of long products price index trend of expansion. The third quarter of this year, long products price index trend has been weaker than the price index sheet, and long products price index accelerated in mid-September to late fall when. Behind this is the real estate industry continues to decline in influence. These defects with the increase in the size of the ingot mold and increasingly serious. On the other hand, osteoporosis, dendrimers and carbides must guarantee the elimination of defects such as forging a certain ratio, the smaller the ingot is not desirable. For this contradiction, the general approach is to ensure that the conditions under forging ratio, try using small ingots. Because of the small size of the ingot cooling conditions were better, more dense internal organization ingot casting flaw less serious. For high-alloy (eg Cr12 type ledeburite) steel, generally smaller size should ingot, forging ratio by forging methods to ensure.
