Has anyone here seen 1/2 hard 301 SS used for crack or corrosion related repairs to aluminum extrusions subject to cyclic loads?
Seems to me this is high risk for corrosion fatigue and maybe even SCC with any clamp-up issues. Scares me. Not sure where to start with a life knockdown.
I see a lot of repairs on one type that have been done this way. I've been told that some other types (Lockheed, Sikorsky) also use SS in high cyclic stress areas (but P-H maybe?).
AISI 301 is definitely easy to get and fabricate with tight bend radii.
Maybe it's just me. Passivate & prime - good to go?
