ABSTRACT

In this paper, HSS bit, tap, vertical milling cutter, YT15 milling cutter, 9CrSi and Cr12 Mold materials are treated by deep cryogenic. The hardness and red hardness of materials before and after deep cryogenic are tested and contrasted. And industrial production is carried out on the part of tools and molds. The result indicates that deep cryogenic can improve the hardness and red hardness of materials to some extent. It can also improve the wear resistance of materials, which extends the service life of tools and molds. Therefore, the deep cryogenic treatment is one of stong methods to improve the service life of tools and molds.
