joe, you are remarkable.
priceless.
one of your true qualities, is your inability to realize when you are making a complete fool of yourself.
it is humour at its finest.

is it rust or corrosion?
OK, I think we mostly agree that stainless is non-magnetic - I'm therefore almost certain that that is what I have and yet I still have a chemical reaction which looks like rust - any ideas? I have a picture but cant figure out how to display it on this forum.
Do you think this is one of those topics that will go on for pages and pages and pages? Then at the end the OP still hasnt got an answer 
Who remembers Legs and Jbonding when they used to argue about plastering
Happy days.

Can you actually get SS angle bead? I’ve not a pro but have never seen it nor Aluminium Alloy for that matter! It’s almost certain the beading is galvanised steel, why would anyone use anything else!
If it’s corroded, it’s likely to be at the corners where the beading was cut & the exposed steel edge has been subjected to dampness over a period of time. If the beading was fitted, plastered over & painted correctly, there will be insufficient moisture to allow corrosion to continue; if it has, dampness seeping through from the external wall seems like a likely place to look, especially on a window reveal.
It’s a long time since I’ve had need to consult the Iron Carbon diagram & I don’t really want to get drawn into the current squabble but, from memory; the best grades of SS (usually marine & medical) have high Nickel/Chromium content & are non magnetic but the tensile strength & hardness is not particularly good. For applications where tensile strength &/or hardness are important (fixings & cutlery etc.), a much lower Chromium or Nickel content is used but the molecular structure is not Austenitic as John D highlights in his Steel Mill quote so they are not true SS, they are a steel alloy &, hence, are slightly magnetic.
Come on guys; give the poor op a chance with his question!
