    abstract = {The effect of solution annealing temperature ranging from 1050-1100°C and aging at 480°C on the
microstructure, mechanical properties and pitting corrosion resistance of Super Duplex Stainless Steel (SDSS)
casting were investigated. Obtained results showed that the content of ferrite phase slightly increased as
decreasing of austenite phase. The ε-Cu was observed into incoherent type after solution annealing and
coherent type after solution annealing and aging at 480°C. The small particles of the g-phase dispersed in ferrite
matrix increase their hardness and diminish corrosion resistance of ferrite phase. Especially, the little negative
hysteresis and high breakdown potentials determined from cyclic potentiodynamic polarization curves of SDSS
showed that the high pitting corrosion resistance were obtained for the sample with both annealing and aging.
The mechanical properties of the SDSS casting were also investigated such as hardness, micro hardness and
impact strength. The value of hardness and impact strength of SDSS casting which were solution annealing
at 1100°C and aging at 480°C were 295 HB and 77 J, respectively.}
