HEYE Special Steel Co.,ltd. is a specialized in manufacturing high speed tool steel integrated with production、R&D and National Engineering Research Center for Advanced Steel Technology capable of producing high quality tool steel. The cooperation equiped with IF, LF, VD melting process, SF, PM special forming process and unique forging process and other metallurgical processes to develop and produce hot work tool steels with high hot strength, high wear resistance with high isotropy properties. These steels can be chosen to be the tool materials applied under difficult working conditions to get longer tooling life. More homogeouse or less segregation of the hot working tool materials developed through SF, PM, special forging processes to meet the high demand of the modern industry. HEYE started from pilot production of GM, 65Nb, H42, 012Al, H13, Y33, HM1, H21 etc., to the new development of HIT H413, H414, H418 and U2 series. the company has established the brand name in the hot work tool steel in many application areas such as diecasting, forging and extrusion.  Further more, HEYE is putting effort in getting customer intimacy to solve indivisual problems by helping customers to choose right steel grade and right heat treatment process.
