Detailed Product Description: | Yong Wei mold steel, imported S500, S500 provided by Yong Wei Zengcheng steel mold. We are Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) located: Dongguan, Guangdong specializes in: mold steel, DC53, SKD11.SUS440C, SUS420 structure, namely the complex mold sliders, lifters, straight top block and so on. Structure design is very critical, related to the life of the mold, the processing cycle, costs, product quality, etc., so the design of complex integrated capability of the core structure of the mold designers are higher, as the pursuit of simpler, more durable, more economical design. Compressive yield strength and compression bending strength: the strength of the mold is often subjected to high pressure and bending in use, thus requiring the mold material should have a certain compressive strength and flexural strength. In many cases, the compression test and bending test conducted conditions close to the actual operating conditions of the mold (for example, compression mold steel measured yield strength and punch work has shown more consistent deformation resistance) . Nitriding process currently used ion nitriding, high frequency nitriding and other technology. Ion nitriding nitriding time can be shortened, and the availability of high quality nitrided layer. Ion nitriding can improve the casting mold corrosion resistance, abrasion resistance, thermal fatigue resistance and adhesion. Carbonitriding be carried out in a gas or liquid medium, medium, small diffusion layer brittle, permeation time is much shorter than the nitriding time. Die casting, hot extrusion die through after carbonitriding can significantly improve the thermal fatigue performance. Carbonitriding for cold heading die, cold extrusion die, Die, drawing die and so have a very good application effect. 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. Die S500 wholesalers mass production, in order to reduce the wear S500 mold price, in addition to the surface hardness of the cavity, the surface roughness is also an important condition. Hypoeutectoid steel for adoption. In order to refine the grain, homogeneous, eliminate stress, reduce the hardness 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, cold resources are more abundant. Slowdown in downstream demand growth, lower purchasing volume S500 material 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. |
