Tungsten hot work tool steels are of different types, namely, H21 to H26 types. These hot work tool steel have similar characteristics to that of high speed tool steel. The primary alloying elements in tungsten hot work tool steel 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 tool steel. Breakage of the tungsten hot work tool steel can be reduced if they are preheated to operating temperature before use. Thermal shock resistance and toughness of these hot work tool steel can be improved by reducing the carbon content.
