AsiaVest steel mold (Figure), SKH-9 material, Anxiang SKH-9 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! Mold steel manufacturing is the basis for the entire industrial manufacturing technology and equipment, electronics, automotive, electrical, electronics, instrumentation, home appliances and telecommunications products, 80% to 90% of the parts have to rely mold forming, determines the shape of the mold of these products shape, processing quality and precision mold will determine the quality of these products. The future of China's mold industry after the restructuring, will be increasingly high precision molds, mold steel requirements are also increasing. For a quenching medium cooling during the quenching operation. Mainly used in high, medium carbon steel parts, in order to ensure adequate hardened layer to prevent quenching crack. A process used to reduce the deformation. Commonly used in the water - oil, water - air, oil - air and other media. Slightly removed from the workpiece furnace stay a while quenching into water "cold be quenched" in the air also belongs dual media quenching. From this point of view, on the one hand, this winter seems to be earlier than in previous years, even holding similar to last year's operating margin rate of decline in the raw material market pressures to be overlooked; on the other hand, as of early October, focusing on steel Steel stocks are still up to 15.689 million tons, higher than normal inventory levels of nearly 3 million tons, 2.189 million tons Yijiao same period last year, with the winter near, corporate demand for return of funds to the inventory will increase SKH-9 hardness, In this process may also take the initiative to cut production in order to reduce pressure on the stock of finished products. Taking into account the cuts during the APEC meeting in early November decree Hebei and other places likely to face the SKH-9 manufacturers, if the supply is gradually reduced expectations are confirmed, then the pressure on the raw materials market will be significantly higher. Shoddy material surface is easy to crack because it is blank adobe, adobe many pores, adobe in the process due to the cooling effect of the thermal stress cracks, after the rolling had cracks. 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 SKH-9 providers to 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 prices are so depressed SKH-9, 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.
