EPR measurements in heat-working plants

摘要

This paper reports about experiences of sensitization behaviour of titanium and niob stabilized steels under practice conditions at operating temperature between 340 and 600℃. Pipes, flanges, welds including heat-affected zones are examined for sensitization with help of the electrochemical-potentiodynamic-reactivation-method. Measurements were carried out on-site during plant stoppage at different pipes with diameter between 150 to 460 mm with a set-up measuring cell.
