  • Applications

  • Equivalent Grade

  • GOST 3Х2В8Ф Introduction:

    3Х2В8Ф is one of the hot work, tungsten containing tool steels. The tungsten content is beneficial for hot strength at red heat, although toughness is somewhat reduced. 

  • Soft Annealing

    Heat to 820-840oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 240.

    Stress Relieving

    Stress relieving to remove machining stresses should be carried out by heating to 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

    Hardening

    Harden from a temperature of 1100-1150oC followed by oil quenching or warm bath quenching approx. 540oC. Hardness after quenching is 52 HRC.

    Tempering

    Tempering temperature: 580-700oC.

  • 3Х2В8Ф Tool Steels Application

    heavy-pressing tool (small insertion of the final stamp of the stream, dies and punches for the extrusion, etc.) in hot deformed alloy structural steels and superalloys, mold casting of copper alloys.
