Pengshui ASP23, Yong Wei mold steel, ASP23 suppliers from 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! In the mold production costs, material costs typically account for 10% to 20%, while the machining, heat treatment, assembly and administrative expenses accounted for more than 80% ASP23 suppliers, so the process performance of the mold is affecting the production cost of the mold and manufacturing difficulty of One of the main factors. Steel mold processability, thermal processing performance, refers to thermoplastic processing temperature range; cold performance ASP23 hardness refers cutting, grinding, polishing, drawing and other processing performance. Cold work die steel are mostly eutectoid steel and ledeburite, hot and cold performance is not very good, it is necessary to strictly control the process parameters of hot and cold worked to avoid defects and waste. On the other hand, by increasing the purity of steel, to reduce the content of harmful impurities, improve organizational status of the steel, hot and cold worked to improve the properties of the steel, thereby reducing the production cost of the mold. Tempers mainly used for ultra-high-strength steel, spring steel, forging mold and other uses tempering tempered troostite tissue. This treatment process so that the steel material is the best elastic limit, a sufficient hardness and a relatively high strength level. Able to completely eliminate the quenching stress, forming part of the granular carbide. The heating temperature is usually 350-500 ° C heat. From the perspective of the current combination, the recent rapid rise in futures prices was mainly due to the replenishment of steel on the spot after a certain boost to the National Day, iron ore futures took the opportunity to repair the structure caused by the depth of the premium, and with continuation rhythm of the market, after a high premium is expected to be further narrowed. However, the structure of the iron ore futures premium actually reflects market expectations of future price of iron ore, futures premium to the spot market is relatively bearish on behalf of future ore prices, this structure since before iron ore futures on has been formed, and with the continued increase in international iron ore supply, as well as the decline in China's steel output growth, the future of the international iron ore market oversupply situation has been basically formed, futures prices continued premium to the spot also in line with common sense. Temper brittleness can be divided into first class and second class temper brittleness temper brittleness. The first category, also known as irreversible temper brittleness temper brittleness, mainly in the tempering temperature is 250 ~ 400 ℃, the brittleness disappears after reheating repeated in this interval temper brittleness no longer occur, the second tempering Brittle also known as reversible temper brittleness temperature occurring in the 400 ~ 650 ℃, when reheated brittleness disappears, should be quickly cooled, can not stay long or slow cooling in the range of 400 ~ 650 ℃, otherwise it will happen again catalytic phenomenon. The occurrence of temper brittleness of steel alloying elements contained in the relevant, such as manganese, chromium, silicon, nickel produces tendency to temper brittleness, and molybdenum, tungsten has a tendency to temper brittleness and weakening. Die steel, such as 3Cr2W8V, H13,5CrNiMo, 5CrMnMo etc., using higher than conventional heating quenching quenching temperature, can reduce the number of carbides in the steel to improve its morphology and distribution, so that the solid solution of carbon in austenite distribution technology, after quenching can get more lath martensite in the steel to improve its fracture toughness and thermal fatigue resistance, thus prolonging the life of mold. For example, one hot 3Cr2W8V steel extrusion dies, conventional quenching temperature is 1080 ~ 1120 ℃, tempering temperature is 560 ~ 580 ℃. As we all know, this year the real estate market is very weak ASP23, prices continue downward, closing the sluggish performance of the economy as a whole form a larger pressure, to a certain extent, restricted economy continues to develop. Thus, in the country have relaxed the restriction after ASP23 rod, the central bank introduced the New Deal in the end of September: the lower the lending rate is 0.7 times the benchmark lending rate, to have two sets and more housing and home loans have been settled respective families, but also to apply loans to buy housing, banking financial institutions should carefully grasp based on the borrower solvency, credit conditions and other factors and to specify the down payment ratio and lending rates
