 Asp 60 is manufactured by powder metallurgy ASP technology with super high-carbon high-vanadium high-alloy high speed steel. 

 ???? Benxi Iron and Steel is atomized metal powders, compaction, and then the hot forming to the required size. Uniform structure so that it has a unique combination of properties. · A good grinding performance · Good heat dimensional stability, good toughness, very good red hardness very good wear resistance 

 Application 

 ????? ASP 60 is particularly suitable for used in rigid steel wear resistance and red high single-point cutting tool. Such tools are knives, cut off the lathe tool, forming the knife, cold work tool and the tool used for machining machining difficult materials. ???? Lower the machining performance of the ASP 60 in the annealed state, tool manufacturing allows ASP 60 will be reflected in the ultimate tool for good performance. For example: the end mill, the shape is simple but extremely long-lived cutter or a simple cold work tool. 


 Special properties 

 ????? ASP 60 can reach a very high hardness and red hardness. In addition, the ASP 60 and other ASP series steel like the hardening process, the size and shape has the advantage of good stability. Moreover, regardless of size, have the same toughness. The machining performance is lower than other high-speed steel. The grinding performance is superior to other high-alloy high-speed steel, slightly less than the ASP 30.

 Manufacturing tools 

 ????? ASP 60 can be the same as other high-speed steel, thermoplastic forging forming, machining, grinding, EDM, welding and polishing. However, to avoid the cold forming. ???? Grinding and EDM can be well applied to high-alloy ASP 60. Grinding, the need to avoid overheating of the local surface. The grinding wheel suppliers can select wheel recommended. Machining can choose to use the tungsten steel or high-speed steel cutting tools. 
 Bending strength 

 ????? Bending strength is used to measure the toughness of the material. This chart shows the toughness and hardness of the material can be controlled by different quenching temperature. 


 The bending test specimens quenched after 5mm diameter round bar three times at 560 ℃ tempering, thermal insulation of one hour each. Rmb = limit bending strength KN/mm2 of ± 10%. Reb = the bending to yield strength KN/mm2 of ± 5%. HRC = Hardness value 1HRC
