Abstract
In the main frame of the PEC joint venture the austenitic stainless st eel ASTM A240 Tp 316 was tested over a wide range of characteristics. Particular emphasis was given to the temperature range between 550 deg rees C and 650 degrees C, in which creep testing up to 20 kh and creep crack growth up to 18 kh including influences due to specimen geometr y, crack starter notch machining and ageing heat treatment. Finally a GTAW+SMAW weld was tested in creep crack growth and revealed crack nuc leation times shorter than all other tested conditions but a crack gro wth behaviour similar to the aged condition.
