Hi,
I am designing a shaft that needs to be submerged in water with something like 500 ppm of chlorides (KCL, NaCL, etc). PH is around 8.0. Temperature is ambient. We have used SST 416 and evidenced pitting (stress corrosion cracking?). We moved to 17-4 H1025 with great results but currently we need something with higher strength. I am thinking to try 440C but haven't found any good information on its performance under chloride environments. Do any of you have used 440C for this environment? Do you know of any good source that I can check?
Many thanks,
