The influence of austenitzing in heat treatment routines of two different injection pipe steels (1.4034, X46Cr13 and 1.4021, X20Cr13) was evaluated. Steel coupons were austenitized at different temperatures (900-1050 °C) for different lengths of time (30-90 min) before quenching and annealing prior to long term corrosion experiments (60°C, 100 bar, artificial brine close to a CCS-site in the Northern German Basin, Germany). In general, fewer pits are found on X46Cr13. Comparing steels with 13% chromium each the higher carbon content of X46Cr13 (0.46% C) results in a lower number of pits compared to X20Cr13 (0.20% C). It is found that neither the carbon content of the steels nor austenitizing temperature has much influence, but local corrosion behaviour is most susceptible towards austenitzing time. 2016 Pattaya Conference Proceedings 6th International Conference on Future Environment and Energy (ICFEE 2016) Pattaya, Thailand 23.01.2016 Anja Pfennig Axel Kranzmann eng uncontrolled CCS eng uncontrolled CO2 eng uncontrolled Corrosion eng uncontrolled Steel eng uncontrolled Heat treatment Ingenieurwissenschaften und zugeordnete Tätigkeiten Datei im Netzwerk der BAM verfügbar ("Closed Access") Graue Literatur
