Resumen : The goal of this study was to examine the changes caused in stress corrosion cracking and the critical pitting temperature behavior of a UNSS31803 duplex stain less steel due to variations in the ferrite fraction and the presence of chromium nitride in their microstructure. The steel plates were cold rolled and annealed at 1060 °C. Microstructural variations in the plates were produced by thermal annealing treatments a t1200 °C and 1300 °C. Steel annealed at 1060 °C showed greater resistance to stress corrosion cracking than steel annealed at 1300 °C. Steel annealed at 1300 °C had the lowest critical pitting temperature.
