Tungsten steel DA50_ Yong Wei Zhongxian tungsten steel mold steel _ 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! Isothermal annealing is mainly used to refine the organization of carbon steel, alloy steel forgings, stampings, etc., reduce the hardness to prevent white spots and even organizations. Annealing is heated to 30-50 degrees Celsius above Ac3, isothermal above Ac1 20-30 degrees Celsius, insulation can be adopted in accordance with the fully annealed. Cooling rapidly cooled to below Ac1 isotherm. Isothermal time more important: Carbon 12 hours, alloy 3-4 hours. And so the end of the warm time, remove the air cooling. At this stage the uproar of foreign anti-dumping actually more than the size of the domestic mills is not much impact, after such regular tungsten steel mills producing products, reliable quality at a fair price in the eyes of foreigners peers gold is still very full, channel Under normal circumstances the conduct is also, not only does the anti-dumping storm blowing its body, but also the opportunity to get rid of the market in shoddy, disrupt the black sheep of the international market trading order. So basically these mills sit back, quite see Pretrial blossom, since the extra cash I chic style. Shantou increasingly large steel mold, especially in increasingly large molding parts, in order to improve production efficiency, a multi-cavity mold CD650 tungsten steel, so the large modules steel demand will increase year by year; precision molds increasingly high requirements for the quality of steel Good, high dimensional accuracy, good stability; the demand for plastic mold steels, die casting mold steel is increasing; the demand for high-grade steel mold growing increasingly surplus low-grade tool steel. Current tungsten steel A10, China's mold industry is entering an important period of development. Manufacturing development of the automotive industry in particular, to promote domestic mold growing market, foreign customers to purchase the mold of an increasing number of international mold manufacturing gradually to the trend of China's shift is very obvious. China Die & Mould Industry Association predicted that this year the market continues to improve at home and abroad mold, mold industry in China will maintain an annual growth rate of about 20%. Precision plastic mold has been able to produce plastic molds for cameras and mobile phones, multi-cavity mold and a small modulus gear accuracy of 5 microns 7800 cavity plastic mold. Cold mold material alternative technologies require cold mold material has the strength, toughness, wear resistance, fatigue resistance performance and bite. S136 cold mold using the high carbon carbon steel, low alloy steel or cast iron after Laser Transformation Hardening replaced by the traditional process of high-grade materials, the presence of a wide range of applications of space technology. S136 Although widely used high-alloy steel cold mold has a unique wear-resistant alloy carbides effect, but Laser Transformation Hardening its dispersion strengthening, distortion enhancement, processing and heat treatment process without oxidation and decarbonization have no other strong working layer CD750 tungsten steel rod, S136 can compensate for the effect of high wear-resistant alloy steel has a carbide. Steel prices in mid-September to late 'cliff-style "down. From the third quarter of the overall steel trend, July ~ August, showing an overall decline in steel prices, the average price declines five major varieties of the nation's major markets for 2 yuan / ton to 39 yuan / ton. In early September prices rose slightly after the round, the overall steel prices (excluding prices of cold rolled coils outside) along with presenting "cliff-style" down, steel refresh the past 10 years the price low, the national average price of long steel products 50 yuan / ton to 70 yuan / ton decline, hot rolled coil and plate average price 50 yuan / ton to 60 yuan / ton decline.
