Summary

Austenitic steels are widely used in construction of pressure vessels for low-temperature service down to 4.2 K. Some of these steels do not have austenitic stability and are therefore susceptible to phase transformation from ductile austenite to brittle martensite at low operating temperatures or as a result of cold working (straining). Investations have been made to evaluate the changes in properties of two steels and weld deposit obtained with filler metal when soaked in liquid nitrogen and liquid helium. Special attention was given to the changes in impact toughness.
