AsiaVest steel mold (Figure), DAC mold steel wholesale, Panzhihua DAC is provided by the steel mold, Dongguan City An Yongwei 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 according to their working conditions, general requirements to keep in 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 while the DAC, the plastic deformation resistance may have significant differences between the composition and organization of different kinds of steel 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. DAC processing and heat treatment of high alloy tool steel mold wholesale steel, low alloy tool steel than is usually more difficult, so the mold manufacturing costs are higher, while the ASP-23 high speed steel powder its machinability, manufacture than traditional methods Fortunately, high-alloy tool steel, dimensional stability heat treatment is relatively good, and easy to predict. More because of ASP-23 high hardness, good toughness and high-temperature tempering characteristics, especially for surface treatment of DAC hardness, very easy to process. Two heating changes when heated to room temperature and tissue transformation of austenite and martensite transformation upon heating tempering; three cooling transformation of austenite to pearlite transformation of austenite to bainite transformation of austenite to martensite transformation. So according to these theories and data can be formulated heat treatment process or the operation system. Of course, some practical experience and operational capacity is a must. Recent domestic policies to stimulate the market demand for the introduction of intensive Treasury canceled coal import tariff on the market sentiment to form a strong boost. APEC summit to be held in Beijing DAC rod, environmental management efforts to increase steel production is expected to bring, but also the formation of the steel market confidence boost. Recently black chain futures eye-catching performance, iron ore futures trading, futures also just under 1 yuan thread limit, the spot businesses will significantly push up the market mainstream offer short term cumulative increase of nearly hundred dollars. However, the price level after a turnover and no timely follow-up, lower procurement initiative slowdown, the business mentality tends to be cautious, resources to pull up too fast quote section loose. Given the current stocks are low, specifications shortage and other factors on the current market price is still strong support, short-term price or low balance finishing.
