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 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. The aim is to complete the other phases in the alloy is dissolved in austenite DAC suppliers, to form a single-phase solid solution alloys. 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 are also still high DAC, pressure also limits the financial aspects of the procurement activities of enterprises. China at this stage is still in the demographic dividend period, there is a lot of labor, lower labor costs relative to developed countries; market, the mold industry, the Ministry of steady advances in traditional markets and actively open up emerging markets, even in the past ignored edge of the market has also been development, which are for the mold industry to develop a broad market space; In recent years, the Chinese government has issued a series of policies to support the casting, the development of domestic metal casting industry, but also to create a good development space for the mold industry. Shoddy die steel prone to folding. Folding is formed on the surface of a variety of die steel fold, this defect often throughout the product's portrait. The reason is due to shoddy manufacturers of folding the pursuit of high efficiency, reduction is too large, resulting in the ears, it creates a rolling when folded down, the product will crack when folded bend, making the strength of the mold steel declined significantly. October is the best month of the domestic infrastructure construction, but also the only good outdoor construction during the year "days"; in infrastructure in order to complete the annual task of pressure, I think, this time next month or so, is the outdoor infrastructure Project construction season, at rush period, driven DAC price, Xianluo other construction steel demand there should be a more centralized point of release. The September manufacturing PMI index is relatively stable, indicating that the domestic economy is stable, but lower portion of the index also reflects the economic side there is still downward pressure in the future. At the same time, good bad macro intertwined; relax or stimulate the property market, real estate credit market confidence, but it is difficult to form a clear effect in the short term.
