Processing and heat treatment of high alloy tool steel, low alloy tool steel than is usually more difficult VK manufacturers, mold manufacturing costs and therefore higher import VK mold, and ASP-23 CPM its machinability, than the traditional method of manufacturing Fortunately, high-alloy tool steel, dimensional stability heat treatment is relatively good, and easy to predict. But also because ASP-23 high hardness, good toughness and high temperature tempering properties, 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. Vacuum heat treatment technology is developed in recent years a new type of heat treatment technology, it has the characteristics of mold manufacturing is urgently needed, such as to prevent oxidation and decarburization heating, vacuum degassing or outgassing, eliminating VK embrittlement material, thereby improving the material (parts) ductility, toughness and fatigue strength. Vacuum heating is slow, small temperature difference between inside and outside parts and other factors, determines the vacuum heat treatment process caused by deformation and small parts. The chemical composition of the steel mold VK, the number of factors grain size, purity, carbides and inclusions, morphology, size and distribution, as well as the microstructure after heat treatment systems such as tool steel and heat treatment were obtained for great impact toughness. In particular purity and thermal processing of steel deformation transverse impact toughness is more obvious. Toughness, strength and wear resistance are often conflicting. Therefore, a reasonable choice of the chemical composition of the steel and the use of reasonable refining, thermal processing and heat treatment processes to make the mold material wear resistance, strength and toughness to achieve the best fit.
