Conclusions

  1. 1.

    In the manufacture of sintered R18 steel by DHP, the optimum process parameters are: treatment temperature 1250–1280°C, specific work of pressing 25–30 kg−m/cm3, and holding time 10 min.

  2. 2.

    Sintered steel produced by this method has a homogeneous, fine-grained structure free from carbide segregation.

  3. 3.

    The useful life of sintered steel tools is twice that of tools made in standard steel.
