| Abstract: | The article investigates the structural strength of the metastable austenitic steel 03Kh16N9M2 and of the steel of the transition class (martensite + residual austenite) 05Kh14N5DM in the temperature range from 293 to 77°K for the purpose of determining their suitability for large components in cryogenics. It is shown that for their characteristics of impact toughness and low-cycle fatigue steel 05Kh 14N5DM containing up to 15% residual austenite cannot be recommended as material of cryogenic structures operating at 77°K.Translated from Probiemy Procnnosti, No. 5, pp. 43–50, May, 1993. |
