Detailed Product Description: | Sweden Assab mold steel, die steel Tsu, John Granville 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! Isothermal annealing is mainly used to refine the organization of carbon steel, alloy steel forgings, stampings, etc., reduce the hardness to prevent white spots and even organizations. Annealing is heated to 30-50 degrees Celsius above Ac3, isothermal above Ac1 20-30 degrees Celsius, insulation can be adopted in accordance with the fully annealed. Cooling rapidly cooled to below Ac1 isotherm. Isothermal time more important: Carbon 12 hours, alloy 3-4 hours. And so the end of the warm time, remove the air cooling. In fact, foreign anti-dumping on the domestic mills is not much more than the size of the impact at this stage the uproar, after all, this type of steel production product regular, reliable quality, reasonable price in the eyes of foreigners peers gold is still very full and formal channels the conduct of the case is also mold steel, not only does the anti-dumping storm blowing its body Hitachi mold steel, but also took the opportunity to get rid of the market in shoddy, disrupt the black sheep of the international market trading order. So basically these mills sit back, quite see Pretrial blossom, since the extra cash I chic style. Shantou increasingly large steel mold, especially in increasingly large molding parts Bluff mold steel, in order to improve production efficiency, a multi-cavity mold, so a large block of steel demand will increase year by year; precision molds increasingly high requirements of steel Good quality, high dimensional accuracy, good stability; the demand for plastic mold steels, die casting mold steel is increasing; the demand for high-grade steel mold growing increasingly surplus low-grade tool steel. Compressive strength and the compressive yield strength of the mold is often subjected to high bending strength and bending stress in use, thus requiring the mold material should have a certain compressive strength and flexural strength. In many cases, the compression test and bending test conducted conditions close to the actual operating conditions of the mold (for example, the measured compressive yield strength of the steel mold and punch work has shown more consistent deformation resistance) . Another advantage of the bending test is to be absolute value of the variable, and can be more sensitive to reflect differences in deformation resistance under different heat treatment and texture between different kinds of steel. Alloy steel and high carbon steel parts carbon ratio, high carbon steel tools, molds and other parts, in order to reduce deformation and cracking, often using isothermal quenching methods. The finished piece is heated rapidly quenched slightly above the horse's transformation began isothermal isothermal bath furnace to complete bainite transformation occurs, get lower bainite isothermal quenching operation called quenching. Austempering get is bainite rather than martensite. But with considerable good mechanical properties. The main factor is the restricted cross-sectional size of the workpiece. From the third quarter of 2014, the number of available days of average inventory of iron ore, the overall downward trend was shock, mainly due to new production overseas iron ore market is significantly higher than the new China, the largest iron ore demand in consumer countries supply and demand pattern of international iron ore market has undergone substantial changes. Second, the United States Fen cola mold steel, subject to adjustment Chinese real estate industry for 10 months, consumer confidence in the market share of the largest iron and steel industry, building materials demand suffered a serious setback, combined with the previous two years, the steel trade and industry has been a continuous shuffling, steel terminal both weaker demand and trade aspects of the formation of a great impact on market confidence, the steel industry related commodity spot prices hit a low point this year, futures prices also repeatedly refresh the lowest since listing. |
