High-speed steel ASP-23 Classification of high-speed steel powder 
 Powder high-speed steel with the traditional high-speed steel manufacturing process different is that the differences between on and add some lack of metals, the system can also be a variety of on-demand constituent elements of melting steel material. Roughly the same as traditional high-speed steel into Mo (molybdenum) system and W (tungsten) is two large-scale system. Mo system better material toughness, W series better wear resistance materials, high temperature hardness, impact resistance is strong. 
 The heat-treated high speed steel powder 
 The use of any steel quality, most depend on the selection and heat treatment conditions. Mo system in general high-speed steel powder quenching temperature is not higher than 1200 ℃ (the manufacturers of the components have different high and low). W Department of powder high-speed steel hardening temperature is not higher than 1240 ℃. Powder particular attention to the success of high-speed steel heat tempering process. Mo system should be to prevent heat-treated high speed steel powder Mo element "lacuna" phenomenon. 
 High-speed steel of the grinding powder: 
 A grinding wheel choice: to choose a good wheel cutting force, such as CBN grinding wheel. 
 Second, to prevent overheating of grinding: grinding to prevent the local temperature is greater than the tempering temperature, preferably wet. 
 Third, to prevent the grinding residual stress generated when: Every time the power is not too large, the normal amount of feed every time does not exceed more than 0.03m / m, and maintain regular grinding wheel refurbishment, cut sharp, clean up debris and grinding is done need a good grinding task. 
 Powder high-speed steel of the wire-cutting: 
 Line cutting through the workpiece will have a "discharge white layer" should be removed to raise the life expectancy. 
 First, the wire cutting and then after finishing, and finishing times more the better, especially the increase in thicker materials. 
 Second, try to slow down cutting lines, and reduce the current. 
 Third, after finishing the necessary parts polished to eliminate the discharge white layer. 
 Powder high-speed applications: 
 Powder high-speed steel for high abrasion resistance, good toughness, very good piece to be machined, and can be ground to very smooth surfaces, and so on .... 
 First, replace the traditional high-speed steel for a variety of forming tools. 
 Second, extensive use of precision continuous die, deep drawing mold and mold analysis bending. 
 Third, for the need of mechanical wear (easy to process than the tungsten carbide). 
 Fourth, the need for surface materials such as mirror-easy off more heat-resistant material. 
 Fifth, for the size to be stable, long size should not be used during changes in the semiconductor light-emitting diode die and the body and so on.
