Detailed Product Description: | The carbon content of the steel and alloying elements have an important impact on the quench cracking tendency of steel. In general, with increasing carbon content of martensite, brittle martensite increases, reducing the brittle fracture strength YK30 steel, increasing the tendency of quenching cracks. When the carbon content increases, thermal stress on weakened YK30 suppliers, stress affect tissue enhancement. When quenching in water, the surface compressive stress of the workpiece becomes small, and the maximum value of the tensile stress near the middle of the surface. When quenching in oil, the surface tensile stress becomes larger. All these have increased the quench cracking tendencies. Die steel by cryogenic treatment (-196 ℃), can improve its mechanical properties, some die after cryogenic treatment significantly increased service life. Cryogenic mold steel material can be YK30 between quenching and tempering processes, but also for cryogenic treatment after quenching and tempering. If you still retain residual austenite in quenched and tempered steels, then after cryogenic treatment remains tempered once again. Cryogenic treatment can improve the wear resistance of steel and temper resistance. Cryogenic treatment not only for cold mold, can also be used for hot work die and carbide. The new high-performance cold work die steel SLD-MAGIC performance increase die life and reduce the total cost of production molds and shorten delivery of respect shown considerable advantage. Mainly reflected in the following aspects: - abrasion resistance: The maximum hardness HRC62 its wear resistance increases by about 35% YK30 steel die life greatly improved. - Surface treatment of: Surface treatment adhesion film (CVD and other methods) increases by about 30%, high-strength steel to prevent bending, stretching and other scratches generated during forming. - Heat Treatment characteristics: heat-inch variant was reduced by approximately 40%, the deviation shape will be improved. For the size of the heat treatment and surface modification treatment is less, reduce the repair time. - Cutting: the cutting resistance increases by about 35%, based on improving processing efficiency, shorten the processing time in the mold manufacturing. More wear resistance, heat characteristics, surface treatment resistance, machinability characteristic values ??is carried out with the company representative data to compare the material SLD8 possible and actual product resulting property values ??differ slightly. Aging is an important heat treatment operations. The workpiece is heated to below the solubility line, relatively long periods, so that part of the solid solution decomposition, chemotaxis determinate. Sometimes the aging process so that the hardness is improved, so that the hardness of the material can sometimes be reduced. Using, respectively, depending on the material composition, heating temperature, holding time and other factors. Aging such as cast iron may be at a relatively low temperature, aging the aluminum alloy at about 200 degrees Celsius. China Steel Association data show September 29 direct imports of iron ore 62% grade ore CIF dry powder for $ 78.01 / ton. September average price of $ 82.49 / ton, while the price of imported iron ore was in the beginning of $ 130 / ton, 2011 more was as high as $ 170 / ton. The reason why iron ore prices fell sharply, mainly due to China's domestic demand is weak, while iron ore production is increased, the supply of new large scale.
