Good machining surface corrosion and corrosion resistance: easy pattern formed plastic parts, and some plastics, such as polyvinyl chloride in hydrochloric acid gas generated during the molding of the cavity is corrosive. So for corrosive gases used in plastic, to consider the corrosion-resistant steel is good. To a reasonable choice of the chemical composition of the steel and the use of reasonable refining, thermal processing and heat treatment process SKD62 molds to make the mold material wear resistance, strength and toughness to achieve the best fit. Strong wear resistance steel mold, in addition to steel mold steel also has the ability to thermal fatigue. Hot work die steel under service conditions in addition to cyclical changes in load, but also subjected to high temperatures and periodic thermal shock effect. Compare SKD62 quenching atmosphere under vacuum oil quench hardening mold surface is relatively uniform, but slightly higher, mainly due to the vacuum heating SKD62 suppliers, tool steel surface was an active state, not removal, no oxidation impede cooling film. Heating under vacuum, the surface of the steel degassing effect, and thus has high mechanical properties, the higher the degree of vacuum in the furnace, the higher the bending strength. Vacuum quenching, the fracture toughness of the steel increased die life generally increased by 40% to 400% higher than the conventional process, or even higher. Cold mold vacuum hardening technology has been more widely used. 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%, a substantial increase die life. - Surface treatment of: Surface treatment adhesion film (CVD and other methods) increases by about 30%, to prevent bending SKD62 high strength steel sheet, stretching 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.
