Stainless Steel Rusting
Stainless Steel Rusting
(OP)
I was wondering if anyone could describe what is happening in the attached picture. The parts are cast stainless CF8 as per ASTM A351 and then machined. We obtained data from an independent lab that showed that the chemisty and physicals were per the standard. The parts were put through an environmental test with humidity and temperature (80°C). Out of 12 units only 3 showed signs of this corrosion.
Could suggestion be made on how to remedy this issue?

Clean them up and passivate in nitric acid and see it you still get the same response.

The last picture looks more like a casting defect to me.
