Conclusions

  1. 1.

    The austenitizing effect of nitrogen in amounts of 0.1–0.2% is manifiest in a reduction of the amount of ferrite in the steel (an average of 0.4% for each 0.01%N). Phases of the type of niobium-vanadium carbonitride and primary nitride of the type of Z phase are precipitated in forged steel 08Kh20N12ABF.

     
  2. 2.

    Alloying of austenitic Cr-Ni-V-Nb steel with nitrogen substantially increases the strength properties, with almost no effect on the ductility. Isothermal holding for as long as 5000 h at 550–580° does not induce embrittlement.

     
  3. 3.

    The corrosion resistance of steel 08Kh20N12ABF is close to that of steels 08Kh18N10T and 08Kh18N12TF.
