DC53 steel _ youyang DC53_ AsiaVest steel mold (View) 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! Hardness is the main technical indicators mold steel, mold under high stress constant desire to maintain its shape and size, must have a sufficiently high hardness. Cold work die steel hardness at room temperature is generally maintained at about HRC60, hot work die steel round bars according to their working conditions DC53 generally required to maintain at HRC40 ~ 55 range. For the same kinds of steel, in the range of values ??within a certain hardness, hardness and deformation resistance is proportional; but rather between the composition and organization of different kinds of steel, the plastic deformation resistance may have significant differences with the same hardness value. For austenitic stainless steels, austenitic precipitation hardening stainless steel or other alloys using conventional heat treatment solution treatment methods. Its purpose is to the other phases in the alloy is completely dissolved in the austenite single-phase solid solution alloy is formed. Also to some extent uniform structure, grain refinement. The method is heated to a single phase austenite region, rapid cooling after incubation (for relatively small size hardened austenitic stainless steel equivalent operation), the temperature of the supersaturated solid solution to room temperature and retained this operation is also called a water toughening treatment . Mills used with the purchase of raw materials to take extremely low inventory strategy, iron ore accounted for as a direct cost of more than 60% of raw materials, of course, is an important object of steel procurement department to monitor the downstream end consumer has not yet seen significant Transit, mills iron ore market is still optimistic about the case, companies will continue to lower raw material inventory policy based. Finally, given the steel industry remains one of the key regulatory and industry regulation, financing borrowing costs compared with other industries also remained high pressure also limits the financial aspects of the procurement activities of enterprises. S136H is the DC53 pre-hard material, but the hardness is not very high, at around HRC30 degrees, do not require heat treatment, S136 steel is hardened material, very soft, need to be used after quenching, after quenching hardness can reach HRC58 degrees . The former requirement ratio for small quantities of injection mold, which is used in large quantities. So usually happen in large quantities, can be ordered S136 steel, different on these two areas, there is a demand of the customer can be the difference between these two areas, which were combined amount of the purchase, so we can save the cost of DC53, there conducive to rational to buy better quality steel! Metal heat treatment requirements for material handling must also have a clear enough understanding. Know the composition of features, performance characteristics, scope critical point, the physical and chemical parameters or characteristics of the material of various materials (here including thermal properties, swelling properties and phase transition has occurred and other information). Domestic part have an influence in the local medium-sized steel mills have begun overhaul before and after National Day, which also makes the availability of resources in some areas to reduce the appearance of tight supply of steel products, while taking into account the ongoing maintenance of large-scale steel mills have not yet formed the size of the domestic steel supply and demand pattern overall temporarily unable to change, but in steel prices continued to fall and the upcoming winter conditions DC53 wholesalers, total domestic steel production is the line into a slow decline. Also, another concern news is that a substantial increase in China's steel exports this year, the domestic supply and demand pressures eased to some extent, but the Government has recently said that next year China's steel export tax rebate policy will be canceled when the steel export growth is expected to occur changes in steel prices will increase the uncertainty of the market outlook.
