Conclusions

  1. 1.

    The ductility of forged semifinished products of steel 03Kh9K14N6M3D is satisfactory in a broad temperature range — from 800 to 1200°.

     
  2. 2.

    During hot working of the metal the deformation is more even than concentrated. For this reason, the reduction of semifinished products of steel 03Kh9K14N6M3D by free forging should be limited to ∼20–30%.

     
  3. 3.

    The increase in the grain size during heating of the steel does not have a negative effect on the hot ductility of forged semifinished products.
