Structural Steels

Conclusions

  1. 1.

    The properties of large components made of chromium-nickel-molybdenum steels, in which it is highly probable that a bainitic component is present in the structure, are determine by carbide precipitation in bainitic ferrite with continuous slow cooling. Preparation of a bainitic structure without carbide provides high impact strength and metal strength in the lightly tempered condition.

     
  2. 2.

    In chromium-nickel-molybdenum steels containing 0.10–0.15% carbon with cooling at a rate of 300°K/h a bainitic structure free of carbide forms.
