Abstract：As one of the essential factors， the microstructure of oxide scales on the duplex stainless steel 2205， is crucial for pickling quality of the hot rolled strips. The investigation and analysis process of the microstructure of different oxide scales on the duplex stainless steel 2205 by OM， SEM and XRD was illustrated. The results show that a lot of cracks were presented on the oxide scales of hot rolled strip， accompanied by local oxide scales falling off， which helped enhancing the pickling speed； the thickness of different scales was about 10 μm. However， the increasing of scale thickness and the surface roughness between the oxide scales and metallic substrates in local region caused difficult pickling of oxide scales； the complex and multiple phase composition (remained Fe2SiO4 and Cr2O3·FeO ) of oxide scales led to more challenging process of pickling duplex stainless steel 2205.
