PM-35 Suppliers | AsiaVest mold steel | Zhongxian PM-35 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! Factors affecting the thermal fatigue resistance of steel are mainly: ① steel thermal conductivity. The high thermal conductivity of steel, a metal mold can reduce the degree of the surface is heated, thereby reducing the tendency of the steel to thermal fatigue. Generally believed that thermal conductivity and cooperation related to the amount of carbon steel, high carbon content when low thermal conductivity, so not hot work die steel with high carbon steel. Commonly used in the production of carbon steel (C0.3% 5 ~ 0.6%) combined carbon content is too low. Causes the decrease in the hardness and strength of steel. Is disadvantageous. Critical point ② Steel. The critical point is usually steel (Acl) is higher. The lower steel thermal fatigue bias. Steel mold steel very tough in the work process, the mold bear the brunt of the load, in order to reduce the use of the process of breaking, chipping and other forms of damage, mold steel requires a certain degree of toughness. The number of die steel chemical composition, grain size, purity, carbides and inclusions, morphology, size and distribution of PM-35 suppliers, as well as the microstructure after heat treatment systems and heat treatment mold steel obtained and other factors have a great impact on the toughness of the steel. Currently, on the whole, China's mold steel wholesale market still lags behind the needs of mold industrial development. According to insiders, mold materials include a wide range, from the general carbon steel, alloy steel, carbon tool steel, alloy tool steel, high speed tool steel SKH-9, stainless steel, refractory alloy, superalloy Non-ferrous metals, etc. can choose PM-35, where the most used most of the most common alloy tool steel mold steel. Crown tripod metal cash to provide VIKING mold steel, ASP-23 high speed steel powder, ASP-60 powder high speed steel. Emery cloth or wire by hand in the physical grinding and dry sandblasting, according to need can use different combinations of cleaning. Mechanical cleaning method is a mature technology, is widely used tire industry. The method has simple, equipment, tools, etc. do not ask, but there are insurmountable flaw: mold will cause mechanical damage and shorten the life of the die; sandblasted die easily clogged vent, after blasting to clear the row pores large workload. Disassembly must die, resulting in high labor intensity, long wash cycle. For the "City of Mineral" This renewable resource recycling sunrise industry, the municipal government attaches great importance, specifically approved the establishment of Mineral Park in Baotou City, Inner Mongolia Baotou Aluminum by Industrial Park Administrative Committee escrow. East River district government seize the country the fifth "Mineral City" demonstration bases declare opportunities PM-35 material, with Aluminum park as reporting units, hand drawn composition of the panel, from material preparation, business support, fight superior support and defense of examinations for approval "City of Mineral" demonstration bases for their efforts.
