Conclusions

  1. 1.

    Microadditions of yttrium to austenitic corrosion-resistant steels lead to formation of yttrium sulfide in place of manganese or iron sulfide, which improves the technological plasticity of the steel.

  2. 2.

    The effect of yttrium on the technological plasticity is greatest in nitrogen-free steel. The smaller effect of yttrium in nitrogen-containing steels is probably due to the formation of hard and brittle yttrium nitride.

  3. 3.

    The effectiveness of small yttrium additions depends on the technique of adding it and its residual concentration in the steel.
