DRX is similar to AISI S7. It has a higher carbon content and is alloyed with 3.25% Cr and 1.4% Mo for emphasis on good wear resistance. DRX is typically used for inserts or smaller molds in applications requiring high production volume, or molds subjected to high-wear condition. It is supplied in the annealed condition and typically heat treated to a hardness of 45 HRC or greater after machining. This datasheet provides information on composition and hardness. It also includes information on high temperature performance as well as forming and heat treating. Filing Code: TS-624. Producer or source: A. Finkl & Sons Company.
