SUS440C stainless steel mold Yong Wei, Lianjiang SUS440C 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! 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, rising exploration 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. China's mold complete the product aids to change the product only after two years, the mold industry is still a young industry SUS440C what is material, it is a sunrise industry. But precisely because of this, and many more private and restructuring of enterprises as the mainstay of the industry mold, after two decades of market hard, there is no shortage partially successful business, but several more are in the initial stage entrepreneurship, that is, in the accumulation of capital and Experience accumulated stage, it is difficult to take into account the deeper consideration and action. Dongguan mold steel, although many companies have further business development planning and ambitious, but this plan and space of the current status quo and mold enterprises do not match their own development, which is more in theory, is difficult to really implement The die if you do not take the road of specialization and standardization, a great deal of hidden sustainable development will be the national economy. In accordance with the requirements of the standard, factory state of mold steel should be used Edison precision hardness testing HBS (steel ball indenter) or (hardness alloy indenter) hardness, and as long as the material has a sufficient size, you should try using force and ball Test conditions. However, mold steel material size larger than usual, not directly in the Brinell hardness test, commonly used approach is the interception of a sample in the steel, after appropriate processing by the Brinell hardness test. SUS440C construction steel market prices stable prices, price stability plate, hot rolled coil market price stability, cold rolled coils, galvanized prepainted market price stability. Today, the Shanghai market Φ8mm High Line mainstream price 2830 yuan / ton SUS440C, unchanged from the previous day; Φ20mmHRB400 rebar mainstream price 2790 yuan / ton, unchanged from the previous day; 20mm plate price is 2880 yuan / ton , unchanged from the previous day;
