ASP30 steel is a kind of tall alloy high-speed steel that contains Co and V, it is to use pulverous metallurgy method, produce by ASP craft. Material supplies condition to see a table into dispenses 1, the physical sex visibility of material is expressed 2. Supply condition chemistry what express 1 ASP30 steel to comprise into dispenses (quality mark) / %CSiMnCrMoWVCoFe1.

The microstructure of this kind of steel is even (1) seeing a picture, integral performance is superior: Grinding sex is good; Stability of the dimension when temper by dipping in water is hard is good; Toughness is good; Hot hardness is good; Wearability is good. ASP30 steel is the high-speed steel that contains Co. This kind of high-speed steel is applicable 10 fashion the tool of much blade cutting that cuts bits, such as twist drill, reamer, tap, milling cutter, broach, roll milling cutter, dig to cut cutting tool to wait, reach apply to tool of odd blade cutting, tool of the point of such as tool, cut reachs figuration tool.
