Conclusions

  1. 1.

    The strength and ductile properties of steel 20KhSTTsR do not depend on its boron content.

  2. 2.

    The hardenability of steel 20KhSTTsR increases 1.5 times to twice when the boron content is increased to 0.005%, a further increase to 0.01% entails a decrease of hardenability to the level of steel without boron.

  3. 3.

    The resistance of steel to brittle (T50) and ductile (at) failure increases with boron content increasing to 0.005%; this is connected with the increased hardenability of steel to a martensitic-bainitic structure.
