Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Because many varieties of plastic, plastic products, requirements differ greatly, for the manufacture of plastic mold material also made a variety of performance requirements. Therefore, many industrialized countries have formed a wide range of plastic mold steel series. Including carbon steel, carburizing plastic mold steel, pre-hardened plastic mold steel, age-hardening plastic mold steel, corrosion resistant plastic mold steels, free cutting plastic mold steel, through hardened plastic mold steels, martensitic maraging steel and mirror-polished plastic mold steel. The main complex shape, acting demanding small size parts including steel parts, carbon steel parts, the relatively poor thermal conductivity of parts made of steel, to prevent deformation of the characteristics important to prevent cracking. Such a situation can be used quenching. Usually salt bath quenching, its temperature slightly below the transition temperature martensite start, so red-hot piece avoid direct rapid cooling, the thermal stress reduction without affecting the amount of martensite obtained. Dongchu willingness inland mills raw materials is relatively high, steel mills along the coast will be appropriately reserves. Available from domestic large and medium steel mills imported iron ore inventory changes in the average number of days of view, 2011 to 2013, during the Spring Festival every year in October to Sweden Assab mold steel, the average number of days available inventory increased 2 days, 18 days and eight days tungsten steel imports, including the fourth quarter of 2011 due to an overall average days of inventory available in more than 30 days of high level, thus replenishment efforts is relatively small. China's mold complete the product aids to change the product only after two years, the mold industry is still a young industry, it is a sunrise industry. But precisely because of this, and many more private and restructuring of enterprises as the mainstay of the industry mold, after two decades of market hard, there is no shortage partially successful business, but several more are in the initial stage entrepreneurship, that is, in the accumulation of capital and Experience accumulated stage, it is difficult to take into account the deeper consideration and action. Dongguan mold steel, although many companies have further business development planning and ambitious, but this plan and space of the current status quo and mold enterprises do not match their own development, which is more in theory, is difficult to really implement The die if you do not take the road of specialization and standardization, a great deal of hidden sustainable development will be the national economy. In accordance with the requirements of the standard mold steel, die steel factory state should use Edison precision hardness testing HBS (steel ball indenter) or (hardness alloy indenter) hardness, and as long as the material is of sufficient size Hitachi mold steel, should maximize the use of force and ball test conditions. However, mold steel material size larger than usual, not directly in the Brinell hardness test, commonly used approach is the interception of a sample in the steel, after appropriate processing by the Brinell hardness test. Construction steel market price stability, price stability plate, hot rolled coil market price stability, cold rolled coils, galvanized prepainted market price stability. Today, the Shanghai market Φ8mm High Line mainstream price 2830 yuan / ton, unchanged from the previous day; Φ20mmHRB400 rebar mainstream price 2790 yuan / ton, unchanged from the previous day; 20mm plate price is 2880 yuan / ton, unchanged from the previous day;
