High alloy tool steel machining and heat treatment QRO-90 rod, typically less than the low alloy tool steel is more difficult, so the mold manufacturing costs are higher, and ASP-23 CPM its machinability, than the traditional method of manufacturing Fortunately, high-alloy tool steel, dimensional stability heat treatment is relatively good QRO-90 wholesale 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.
