Premium cold‐work die & mold steel whose strength and toughness approach those of high‐speed steels. DC53 steel delivers superior wear resistance and fatigue strength—achieving 62–64 HRC after heat treatment, with roughly twice the toughness of traditional D2—extending tool life in demanding cold‐work applications.

Heat Treatment Guidelines
– Preheating: 800 – 850 °C in vacuum or controlled atmosphere; hold until uniform.
– Austenitizing: 1030 °C, hold 10–20 min.
– Quenching: Air cool or vacuum‐quench.
– Tempering: Double temper at 520 – 530 °C for 2 h per cycle; yields 62 – 63 HRC.
