Conclusions

  1. 1.

    Precipitation-hardened alloy 36NKhT Yu has high strength, good ductility, a stable structure, low sensitivity to stress concentrations at low temperatures, and can be used for highly stressed components of cryogenic apparatus.

     
  2. 2.

    Austenitic-ferritic steels 15Kh18N12S4T Yu and 12Kh21N5T are characterized by satisfactory strength, ductility, and toughness at temperatures down to 4°K.

     
  3. 3.

    Steel 0Kh20N4AG10 has low ductility and is sensitive to stress concentrations at temperatures below 77°K.
