  • H21 Tool Steel Tungsten Hot-Work Steel

    IntroductionOther DesignationsMachinabilityHeat TreatmentForgingAnnealingTemperingApplicationsTungsten hot-work steels are of different types, namely, H21 to H26 types. These steels have similar characteristics to that of high-speed steels. The primary alloying elements in tungsten hot-work steels include tungsten, chromium, carbon, and vanadium. They are resistant to distortion when they are air-hardened, and have higher hardening temperature when compared to chromium hot-work steels. Breakage of the tungsten hot-work steels can be reduced if they are preheated to operating temperatur
