Abstract
This paper presents impact test results of austenitic-ferritic weld metal o f the type 10X18H9F3C2 (12% ferrite) and cast base metal of the type 08X20H 10M3C2 (10-32% ferrite) after a prolonged thermal ageing at temperatures 25 0-450 degrees C. The obtained experimental data give the possibility to pre dict impact strength degradation of austenitic-ferritic metal after 10(4)-1 0(5) h exposure and to determine thermal embrittlement.
