Effect of tungsten on the precipitation kinetics and localized corrosion resistance of super duplex stainless steels
Bernås, Mia; Westermann, Ida; Johnsen, Roy; Torres Rodriguez, Cristian; Jernberg, Anders; Qvale, Atle H; Iannuzzi, Manuela (Journal article; Peer reviewed, 2018)Although extensively used in oil and gas production due to their excellent combination of mechanical properties and corrosion resistance, 25Cr super duplex stainless steels (SDSSs) are susceptible to the precipitation of ... -
Influence of Manufacturing Process and Resulting Microstructure on HISC Susceptibility of 25Cr Duplex Stainless Steel Pipe
Johnsen, Roy; Heimssæther, Martin; Gjelseng, Linn; Qvale, Atle H; Jernberg, Anders (Journal article; Peer reviewed, 2019)Due to its attractive combination of strength corrosion resistance and cost 25% Cr Duplex Stainless Steel Pipe is used extensively in subsea production systems. Pipes are made by different production methods. The various ... -
Microstructural evolution during isothermal heat treatment of super duplex stainless steels as a function of tungsten content
Bernås, Mia (Master thesis, 2017)Duplex stainless steels(DSS) and super duplex stainless steels(SDSS) can be described as austenitic-ferritic stainless steels of 22%Cr and 25%Cr content, respectively. The DSS and SDSS are characterised by their combination ... -
Susceptibility to Hydrogen Induced Stress Cracking of centrifugal cast 25Cr Duplex Stainless Steel
Gjelseng, Linn Cecilie (Master thesis, 2017)Testing of the susceptibility towards hydrogen induced stress cracking (HISC) for five 25\%Cr super duplex stainless steels (SDSS) under cathodic protection (CP) in seawater has been conducted. The materials were from pipes ...
