Yong Wei steel mold (Dongguan) Co., SKS3 suppliers, SKS3 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 processing mold when used, is widely used because of the mold, all kinds of mold working conditions vary greatly SKS3 wholesalers, so mold manufacturing a wide range of materials, in the mold material was undoubtedly the most widely used tool steel. From - like carbon structural steel, carbon tool steel, alloy structural steel, alloy tool steel, spring steel, high speed tool steel, heat-resistant stainless steel mold until meet the special needs of maraging steel and high speed steel powder, High alloy tool steel powder and so on. General-use tool steel can be divided into cold die steel, hot die steel and plastic molding mold steel three categories red hardness at high temperature hot work die SKS3 material, required to maintain its organization and stability, thereby maintain a sufficiently high hardness SKS3, this performance is called red hardness. Carbon tool steel, low alloy tool steel is usually able to maintain this performance in the temperature range 180 ~ 250 ℃, the chromium-molybdenum hot work die steel is generally in the temperature range of 550 ~ 600 ℃ to maintain this performance. Red hardness of steel depends on the chemical composition and heat treatment of steel. Mold heat treatment is important to ensure mold process performance. It follows the performance of the mold has a direct impact. Manufacture of precision molds: organizational change is uneven, not completely formed and heat treatment of residual stress caused by excessive mold after heat treatment processing, assembly and mold deformation during use SKS3 suppliers, thereby reducing the accuracy of the mold, or even scrapped. The strength of the mold: the development of improper heat treatment process, heat treatment operations are not standardized or heat treatment equipment status is not intact, resulting in being mold strength (hardness) less than the design requirements for processing.
