HEYE special steel Co., Ltd. is a professional manufacture of high speed steel production, a leader of unit of HSS specialty group, cooperated with National Engineering Research Center for Advanced Steel Technology to set up HEYE Tool and Die Research Center.  HY608A is a kind of cutting tool steel, developed on the base of accumulated experience of decates R&D ,production ,sale and service under the situation of rapid inceasing of alloy and raw material and cost of HSS for the need of reducing cost but meeting required properties of some cutting tools.  A series of low alloy economic steels such as HY608, HY608A, HY609, HY609A etc. have been developed in 2004. All these steels contain less alloy but posess good hot hardness and high second hardning capbility. They can well meet the need of machine saw blade, jigsaw, drill, tap ect. cutting tools. This kind steels are called as cutting tool steels instead of low alloy tool steel for not reaching the basic requirement. HY608A has better price-performance ,its hardness can reach 62~63HRC after being quenched and tempered. HY608 is made via key technology of HEYE high quality HSS production, such as ESR, control of narrow composition and saturation, special forging and treatment process. So it has good toughness and good consistency of treatment.
