Mechanical properties of the high-strength steel 07Kh16N6 at low temperatures
- 47 Downloads
If there are external mechanical stress raisers leading to a state of volumetric stress in the zone of the stress raiser and to increased principal stress σ1 at the apex of the stress raiser within the limits KT=3–4, the lower temperature limit of the use of this steel has to be −196°C;
when there are no external mechanical stress raisers, steel 07Kh16N6 may be used at the temperature of −253°C on the condition that the theoretical stresses were determined according to test results at −196°C.
