SAF 2507 ® is a super-duplex (austenitic-ferritic) stainless steel for service in highly corrosive conditions. The grade is characterized by: Excellent resistance to stress corrosion cracking (SCC) in chloride-bearing environmentsSee all results for this questionsp.info What should the temperature be for SAF 2507 to crack?No cracking occurred on SAF 2507 ®, irrespective of the applied stress. In aqueous solutions containing hydrogen sulfide and chlorides, stress corrosion cracking can also occur on stainless steels at temperatures below 60 °C (140 °F).See all results for this question
The minimum PRE value for SAF 2507 ® seamless tubes is 42.5. This is significantly higher than e.g. the PRE values for other duplex stainless steels of the 25Cr type which are not super-duplex.See all results for this questionsp.info How is pitting corrosion resistance determined in stainless steel?For duplex stainless steels the pitting corrosion resistance is dependent on the PRE value in both the ferrite phase and the austenite phase, so that the phase with the lowest PRE value will be limiting for the actual pitting corrosion resistance.See all results for this questionsp.info Good Chloride Corrosion Resistance 0.2mm 40 Mesh Saf …Introduction 2507/Uns S32750/F53/1.441 Duplex Stainless Steel Wire,The 2507 is a ferrite - austenitic (two phase) stainless steel with excellent resistance to spot corrosion, crevices and uniform corrosion. 2507/U...sp.info Effect of microstructure and passive film on corrosion ...The effect of microstructure and passive film on the corrosion resistance of 2507 super duplex stainless steel (SDSS) in simulated marine environment was investigated by electrochemical measurements, periodic wet–dry cyclic corrosion test, scanning Kelvin probe force microscopy, atomic force microscopy, and X-ray photoelectron spectrometry.
