Yong Wei mold steel | SLD footage | Meizhou SLD8 provided by Yong Wei steel mold. We are Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) located: Dongguan, Guangdong specializes in: When steel, DC53, SKD11.SUS440C, SUS420 usually work forging die mold. Its cavity surface temperature up to 300 ~ 400 ℃ hot extrusion die up to more than 500 a 800 ℃; casting mold cavity temperature and the type of material and the die-casting temperature. As ferrous metal die-casting mold cavity temperature up to 1000 ℃ or more. This high mold temperature will significantly reduce the hardness and strength of the cavity surface, in use, prone to play crib. To this end. The basic performance requirements for thermal die steel is high resistance thermoplastic change, including high hardness and high temperature strength, high resistance thermoplastic change, in fact reflects the high stability of steel tempering. Uniform quality steel components, high tonnage cold shears, cut the head end surface smooth and tidy, but due to poor material SLD8 shoddy material die steel, there are often cut off the head and the end face of the meat of the phenomenon, namely uneven, and no metallic luster. And because of shoddy material product manufacturers cut less head, head and tail will be a big ears. China's mold complete the product aids to change the product only after two years, the mold industry is still a young industry, it is a sunrise industry. But precisely because of this SLD8 prices, mostly private and corporate restructuring of the mold body for the industry, after two decades of market hard, there is no shortage partially successful business, but several more are in the initial stage SLD8 entrepreneurial suppliers, that is, capital accumulation and experience in stage, it is difficult to take into account the deeper consideration and action. Dongguan mold steel, although many companies have further business development planning and ambitious, but this plan and space of the current status quo and mold enterprises do not match their own development, which is more in theory, is difficult to really implement The die if you do not take the road of specialization and standardization, a great deal of hidden sustainable development will be the national economy. In accordance with the requirements of the standard, factory state of mold steel should be used Edison precision hardness testing HBS (steel ball indenter) or (hardness alloy indenter) hardness, and as long as the material has a sufficient size, you should try using force and ball Test conditions. However, mold steel material size larger than usual, not directly in the Brinell hardness test, commonly used approach is the interception of a sample SLD8 on steel, after appropriate processing by the Brinell hardness test. Construction steel market price stability, price stability plate, hot rolled coil market price stability, cold rolled coils, galvanized prepainted market price stability. Today, the Shanghai market Φ8mm High Line mainstream price 2830 yuan / ton, unchanged from the previous day; Φ20mmHRB400 rebar mainstream price 2790 yuan / ton, unchanged from the previous day; 20mm plate price is 2880 yuan / ton, unchanged from the previous day;
