Lately, some chromium-molybdenium-vanadium tool steel for hot work such as drawing of copper, brass and aluminum pipes or angles are used in Europe and America.
A series of experiments were carried out to study transformation point of some Cr-Mo-V tool steels, and afterward, hardness and rate of deformation of samples subjected to different heat treatments were measured. And then, as the tool steel was used for hot work, changes in hardness and impact value at high temperature were also observed.
Moreover, the authors carried out the comparison with W-Cr-V tool steels which had been used hitherto, and ascertained the optimum heat treatment of some Cr-Mo-V tool steels tested in this investigation.
