Effect of microstructure on the corrosion resistance of duplex stainless steels: Materials performance maps

Bernås, Mia; Westermann, Ida; Johnsen, Roy; Lauritsen, Christian; Iannuzzi, Mariano (Journal article; Peer reviewed, 2017)

Although super duplex stainless steels (25Cr SDSS) are extensively used in oil and gas production due to their excellent combination of mechanical properties and corrosion resistance they are susceptible to the precipitation ...
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 ...
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 ...
