HEYE Special Steel Co., Lit. is a specialized high speed tool steel plant integrating production and R&D, cooperated with National Engineering Research Center for Advanced Steel Technology to set up HEYE Tool and Die Research Center. It adopts IF, LF, VD melting process, SF, PM special forming process and unique advanced forging and heat treatment process to design, develop and produce  high isotropy  high performance hot work die steels. These steels take over the weakness of conventional die steel, solve the using problem of high end customer, and raise the die life and price-performance. Non or less segregation new kind of high alloy die steel with even and fine structure can be developed via SF, PM special forming process to solve the die steel problem which is not solved by conventional methods.


According to the application fields of steel are divided into hot forging, die casting mold material series and series of shield cutting tool materials.


(1) Hot forging, die casting material


4Cr5Mo2V (HITH418, HSF1255) has excellent excellent ductility, toughness, higher to, high hardness, thermal fatigue resistance. Applied in the aluminum magnesium alloy die casting, extrusion die.


(2)Shield cutting tool materials


5Cr5MoV(HITH13)  three direction forging and the homogenization technology, 57 ~ 59 HRC hardness, impact toughness can be up to 22J, applied to the harsh conditions of shield machine broken rock knife.
