Conclusions

  1. 1.

    One of the reasons for the sharp reduction of the ductility of hardened samples of ferritic stainless steels is local stress concentrations resulting from α⇌γ transformations in boundary interlayers.

  2. 2.

    The ductility of the hardened material increases after tempering due to relaxation of the stresses that occur during hardening and decomposition of the supersaturated solid solution in interlayers.

  3. 3.

    To reduce the scrap rate of parts drawn from sheets of ferritic stainless steels it is expedient to check the mechanical properties and the microstructure of the steel.
