17-4 data against ASTM B117 350 Hr Test issue ?

hello,

I'm looking for validation that 17-4 stainless will pass the ASTM B117 350 Hr white rust salt spray test. Use is Bar form, and the grade has not been nailed down, if that makes a difference in passing or not.


Please help.
Thanks!

I didn't find the right solution from the Internet.
