Introduction:
Tungsten 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 of 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 that of chromium hot-work steels. Breakage of the tungsten hot-work steels can be reduced if they are preheated to operating temperature before use. Thermal shock resistance and toughness of these steels can be improved by reducing the carbon content.
The following datasheet will provide details of H22 tungsten hot-work tool steels.
Application:
The following are the applications of H22 tool steels:
Hot dies
Extrusion inserts for aluminum and brass
