AsiaVest steel mold (Figure), SKH-9 hardness, Zengcheng SKH-9 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! Steel mold to provide a uniform distribution of the allowance for each tool ensures a constant and high productivity and safety of the cutting process. When ap / ae (axial depth of cut / radial depth of cut) unchanged, cutting speed and feed rate can be kept constant at a high level. Thus, the mechanical action and workload on the cutting edge of change is small, so the heat and fatigue generated less SKH-9 manufacturers, thereby increasing tool life. If the subsequent step is a step of semi-finishing, in particular for all the finishing process, or part of the processing can be carried out no no processing. Constant material allowance is the basic standard high-speed cutting applications. Use coal stove, oil furnace, gas stove, are likely to make the workpiece when oxygen decarbonization box furnace heating the workpiece, measures must be taken to prevent heart increases. In the well-equipped, the best way is to pass into the protective gas, but in the majority of small and medium enterprises, the current can still do so. It describes several simple way, when conditions permit adoption. On the domestic ore market in Hebei iron ore fines prices weak stability operation, part of the large mines to cut prices, market pessimism spread. Imported ore prices rose and then fell, 62% grade Platts iron ore index in the October 23 closing price of $ 79.75 per ton, down $ 1.25 a week. After the National Day holiday, steel replenishment demand rises, iron ore port stocks declined. But SKH-9 clinker, such replenishment needs unspeakable "big bang", steel procurement are still very cautious, both supply and demand is still in a state of stalemate. Regardless of plastic mold, which allows the surface roughness of the cavity is extremely small, are required to be able to do almost a mirror shine. To achieve specular gloss, the main point is that the steel must have not less than 38HRC hardness, preferably 40 ~ 46HRC, 55HRC achieve the best. To achieve specular gloss, the first steel inclusions as little as possible, but can not have a bubble exists, and fibrous tissue uniform. In the mass production of the mold, in order to reduce wear, in addition to the cavity surface hardness, surface roughness is also an important condition. Hypoeutectoid steel for adoption. In order to refine the grain, homogeneous, eliminate stress, reduce the hardness of SKH-9 price of full annealing process. Castings, forgings, weldments and rolling commonly used. The steel is heated to 30-50 degrees Celsius above Ac3, usually carbon steel to 1.5-1.8min / mm; steel to 1.8-2.0min / mm insulation. Then the furnace was cooled to 500-600 degrees Celsius baked. After cooled baked. Near the end, businesses accelerate the phenomenon of increased shipments, the recent local cold-rolled prices dropping again SKH-9, cold resources are more abundant. Slowdown in downstream demand growth, lower purchasing volume does not appear, the current high supply, the greater the market pressure on prices is difficult to rebound. And cold rolled prices are still some gaps.
