Deyang SK5_ _SK5 AsiaVest mold steel sheet 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! 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 of steel, increasing the tendency of quenching cracks. When the carbon content increases, thermal stress on the weakened tissue stress 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 oil quenching SK5 sheet, the surface tensile stress becomes large. 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 steel mold can be carried out between the 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. When SK5 price, different approaches should be taken carefully remove residual injection, available copper rod, copper wire and professional mold cleaners remove residual injection mold and other deposits SK5, then air-dried after injection molds according to different production tasks. Dongguan mold steel disable wire, steel bars and other hard objects to clean, so as not to scratch the surface. If rust spots Dongguan mold steel corrosion caused by injection, to use the grinder polishing and spray on a professional anti-rust oil, then the mold in a dry, cool, no dust at the store. In particular for a tire mold cleaning, mold absorb specific wavelengths of laser energy is very small, will not cause damage to the mold surface contaminants (sulfur compounds, inorganic oxides, silicone oils, carbon black, etc.) to absorb large amounts of energy to be instantaneously inflated, vaporized, away from the mold surface, so as to achieve the cleaning effect. Laser cleaning methods are: 1) Laser dry cleaning method, which uses pulsed laser direct radiation decontamination; 2) Laser + liquid membrane method, which first deposited on the surface layer of the substrate film, and then use laser radiation decontamination; 3 ) Laser + inert gas, i.e., while the laser radiation, with an inert gas purging the substrate surface. When the dirt from the surface of the release, it will immediately be blown gas from the surface, in order to avoid contamination of the surface again. Learn from the advanced mode of cooperation overall development layout, attract industry leaders building demonstration of industrial projects, the introduction of domestic research institutes, construction research collaboration agencies to support the development of relevant policies, and strive to 5 years or so to build the annual turnover in the "City of Mineral" demonstration base 50 billion yuan scale.
