摘要：
The influence of annealing temperature on the pitting corrosion of a super-duplex stainless steel (SDSS) with mischmetal addition was investigated in chloride solution by critical pitting temperature (CPT) measurement. The corrosion behavior is strongly dependent on the microstructure, namely the presence of secondary phases, elemental partitioning behavior and volume fractions of ferrite and austenite. Based on CPT results and alloying rules, the optimal annealing temperature is determined as 1070 degrees C and a guideline for further development of improved SDSS is formulated.
