Dear, Hank Tonnemacher,  In my earlier years I salved quite a few old 
cannons and still have one in my front yard. They all had a a thick 
oxide and carbonate crust and lots of coral. After cleaning them off 
I never saw evidence of urchins burrowing into the iron. I think they 
just burrow into the thick encrustation. Gene
