Conclusions

  1. 1.

    The duration of the oxidation and boiling periods has no effect on the hardenability of ShKh15 steel; the over-all duration of the melt period does have an effect on the hardenability.

     
  2. 2.

    The hardenability of ShKh15 steel depends on the degree of reduction (i.e., on the weight of the ingots). As the weight is increased, given equal rolling diameter, hardenability is increased.

     
  3. 3.

    The dispersion of the carbide phase greatly affects the hardenability of ShKh15 steel.

     
  4. 4.

    Between 0.15 and 0.35% silicon greatly increases the hardenability of this steel.

     
  5. 5.

    The hardenability of steel depends on the carbide grain size in the initial structure.

     
  6. 6.

    The addition of boron (0.004%) and cerium (0.03% has no effect on the hardenability of ShKh15 steel when quenched from temperatures below 900°.
