hi, guys,
I just ordered some stainless piano-hingepins (pn#03-49000). What Aircraft
Spruce delivered were some cad-plated rods. I previously got some stainless
and these were silvery-shiny. I complained at AS and they responded that
their stainless 302 pins truely were cad-plated (?) I never heared about
such. What should cad-plating of stainless be good for?


Assuming that you are going to attach the hinges with standard cadmium
plated AN hardware, it could be there to prevent the stainless steel
using the cad plated attachment hardware as a sacrificial anode.
Stainless and cadmium fasteners do not necessarily mix well looking at
their relative placements on a galvanic series.
