Detailed Product Description: | 420 prices, Yong Wei mold steel, Chengdu 420 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 just include Die, drawing dies, drawing die, pressure die, thread rolling dies, rolling plate, cold heading and cold extrusion die molds. There are steel cold mold, according to the working conditions of its manufacture with 420 rods, should have a high hardness, strength, wear resistance, adequate toughness, and a high rate of penetration, rate of rigid and other process performance. Mold just include Die, drawing dies, drawing die, pressure die, thread rolling dies, rolling plate, cold heading and cold extrusion die molds. There are steel cold mold, according to its manufacturer with working conditions, should have a high hardness, strength, wear resistance, adequate toughness, and a high rate of penetration, rate of rigid and other process performance. As a result of improper processing of steel castings, or surface may be formed within the pores, loose, trachoma, segregation, cracks and other defects in the process of thermal processing technology; in forging blank, it is possible to form a shrinkage, segregation, white point, inclusion material, such as cracks. These defects have a great influence on the quenching cracks steel. In general, the more severe the original defect, the greater the tendency of its quenching cracks. Mold steel manufacturing is the foundation for the entire industrial manufacturing process equipment 420, in the electronics, automotive, electrical, electronics, instrumentation, home appliances and telecommunications products, 80% to 90% of the parts have to rely mold forming, which determines the shape of the mold product shape, processing quality and precision mold will determine the quality of these products. The future of China's mold industry restructuring after 420 materials 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 stock will increase in the 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, Hebei and other places likely to face a decree, if the supply is gradually reduced expectations are confirmed, then the pressure on the raw materials market will be significantly higher. |
