SKH-59 hardness | AsiaVest mold steel | Mianyang SKH-59 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! Special quality steel is especially needed in the production process strictly control the quality and performance of steel, indicators of its quality control provisions in its standard belongs, in representation of the representatives of steel symbol indicates that as A, E, C, etc., foreign steel quality level is not marked, but marked refining methods used or made some improvement, improvement, as expressed by the ESR ESR; VAR G50; VIM vacuum induction furnace; mod expressed as some improvement or the like. The greater the temperature difference between the inside and outside of the workpiece, and thus is easy to cause thermal stress in the heating process causes deformation. So heated pace of cross-sectional size of the work should also be considered: a large cross-section should be slower; on the contrary, a small section of the workpiece, the heating rate can be faster. In the construction steel market, although prices overall still continues to rise, but the increase has been a marked contraction. Shanghai, Jinan and other places t price week rose from 20 to 180 yuan SKH-59, Tianjin, Shijiazhuang and other places have fell in SKH-59 hardness, t price decreases in the 20-70 yuan. Currently, the business confidence have turned cautious, market transactions are gradually shrinking. After the completion of a production cycle, to work on the mold surface, sports, professional guide member coated anti-rust oil, in particular should pay attention to the strength of the stretch with a gear rack mold mold bearing parts and springs of protection to ensure that it remains between the coolant and the mold as production lasted SKH-59 material, cooling channels easily deposited scale, rust, mud and algae, so that the cooling channel cross section becomes smaller, the cooling channel narrows greatly reduced; in top working condition heat exchange rate, increased production costs. Dongguan mold steel processing enterprises should first give each deputy dies with history cards, detailed records, statistics of its use, care (lubrication, cleaning, rust) and damage, which can be found whereby parts, components have been damaged, worn extent size, to provide discovery and problem-solving information, and the mold molding process parameters, materials used in the product, in order to shorten the mold test time and increase productivity. Die stress state at work are complex, such as hot work die is usually subjected to alternating stress at alternating temperature field, so it should have good prevent mold into a soft or plastic state capacity, and In the long-term working shape of the mold remains unchanged, and the dimensional accuracy. Generally finished mold hardness, cold mold often choose, hot die often choose around. It also determines the macroscopic surface copper consumption growth will be affected. Electricity use copper as the largest copper field, the first nine months SKH-59 wholesalers, grid investment grew only 3.55% cumulative power invested fallen by 11.41%. We learned from the research point of view, grid investment growth is less than expected, mainly because: on the one hand, slowdown in economic growth leads to social decline in consumption growth, after the addition of UHV power grid investment, mainly for distribution expansion and transformation of the grid, in the case of electricity consumption growth rate of decline, the number of expansion and renovation project is no longer urgent, resulting in a number of projects in spite of successful enterprises, but did not issue orders.
