Yong Wei steel mold (Dongguan) Co., QRO-90 rod, QRO-90 provided by Yong Wei steel mold (Dongguan) Limited. We are a steel mold, Dongguan City, An Yongwei shop (www.dgyongwei.com) located at: Dongguan specializes in: mold steel, DC53, SKD11.SUS440C, SUS420 for abrasives, the machinery manufacturing sector has been its largest market , accounted for 75% of total market abrasives applications. With the continuing recovery of world economic growth and motor vehicles, motorcycles and industrial production, to the field of transport equipment in 2013 is expected to be the most solid abrasives, the fastest growing market. Coupled with high-performance super-hard grinding wheel in the new field of energy, such as wind power equipment applications, abrasives demand growth in the machinery manufacturing abrasives will be much higher than the overall level of growth. Processing and heat treatment of high alloy tool steel, usually more difficult than the low alloy tool steel QRO-90 material, so the mold manufacturing costs are higher, and ASP-23 CPM mechanical processing, manufacturing than traditional methods Fortunately, the Swedish high-alloy tool steel QRO-90, the dimensional stability of heat treatment is relatively good, and easy to predict. But also because ASP-23 high hardness, good toughness and high temperature tempering characteristics QRO-90 rod, especially for surface treatment, very easy to process. According to the characteristics of different types of cold steel and processed materials, choosing the right and quality mold steel and heat treatment.
