ASP23 hardness, jiangjin ASP23, Yong Wei steel mold 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! Some plastic materials have acid resistance, and some by the addition of a reinforcing agent, or other modifications, such as glass fibers the major damage to the mold, are to be considered during the selection. There is a strong corrosive plastic general election S136,2316,420 a class steel, in addition to the election S136,2316,420 weak corrosive, there SKD61, NAK80, PAK90,718M. Strongly acidic plastic material has: PVC, POM, PBT plastic material has a weak acid: PC, PP, PMMA, PA, single-medium quenching quenching method is the most common, simple operation, equipment, and environmental requirements low. Inadequate water quenching is easily deformed steel ASP23 prices, steel water quenching easy to crack. The method of operation is the end of the holding time of a workpiece into the quenching medium to the cooling capacity of the quenching cooling medium, the cooling conditions in this process depends entirely on the cooling characteristics of the workpiece using the medium. Mills use the advantages of resources, weaknesses ASP23, the stainless steel products do fine well, despite the current market lower, but many businesses is not overly worried, because excellent product quality, while the current market even approaching low, as long as endure, to seize the opportunity to make the anti-hunters also a high probability event. National Day, the iron ore spot market transactions are extremely active in cargo turnover is also continuous heavy volume, Dalian iron ore futures even once the daily limit to close at Platts, the highest index also rose $ 83.75 / ton, the highest in nearly a month highs market sentiment continued to pick up. However, iron ore prices really have bottomed out? In fact, this is also related to the late steel to determine the trend, following the author of the latest changes in the market ASP23 suppliers, as we do a brief analysis. Look forward to all of us to grasp the current market situation changes help. Shoddy material surface is easy to crack, because it's blank adobe, adobe many pores ASP23 manufacturers, adobe in the cooling process due to thermal stress, cracks, crack after rolling there. 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 can not be prescribed by rolling austenite region, the natural properties of 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 to suitably increase the hardness level, 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, iron ore companies also bear certain taxes, in 2014 a quarter of China Steel Association announced corporate tax burden of iron ore mine average rate of 21%, up to 30%, taxes have more than 20 projects.
