SKD61 rod | Conghua SKD61 | AsiaVest 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! 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 to make the mold material wear resistance, strength and toughness to achieve the best fit. Wear a strong supplier of mold steel SKD61, 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. Comparison with hardened SKD61 material under atmospheric and vacuum oil quench hardening mold surface is relatively uniform, but slightly higher, mainly due to the vacuum heating, mold steel surface was an active state, not removal, does not produce an oxide film impede cooling. In vacuo under heating SKD61 manufacturers, the surface of 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. Use square shoulder milling cutter cavity coarse milling, semi-finishing would remove the bulk of the stepped cutting margin. This will allow the cutting force changes, so that the bending tool. The result is to leave uneven finishing allowance, thus affecting the geometric precision of the mold. If you use the tip strength weaker square shoulder milling cutter (with triangular blades), it will produce unpredictable cutting effect. In heat production practice, the work of some of the special shape of the use of large or when the protective salt bath furnace heating method is not easy. If you must use box-type furnace or reverberatory furnace heating, these large or special shape of the workpiece, according to the following methods to prevent oxidation and decarbonization work. The continued strength of the recent rise in construction steel kinetic energy has been significantly weakened, leading regional Beijing, Xi'an prices flat SKD61, exploration up area is also just stay in the individual regions. Currently in Beijing, Tianjin steel prices remained at about 2750-2780 yuan, hot-rolled coil, cold rolled coil and plate market prices fell slightly accelerated momentum, Handan hot-rolled coil prices continue to refresh the current National Low 2920 Yuan, lock the current steel plate market price is still stuck in 2830 yuan, but the latest orders is less than ideal spot market mainstream, the lowest price is the probe to the 2830-2850 yuan, cold rolled coil market price adjustment region is today gradually increased.
