I was given unknown commercial catalytic converter.
It weighed 30lbson S.S substrate .
I removed a 5lb sample and soaked in hcl, changing hcl about every 2-4 days .
After about 2 weeks the hcl digested the metal wafers but a couple days before the last of S.S. seemed to be stuck or bonded together with a bunch of white strips of metal that had a little shine .
I have uploaded the pics of 5lb sample and pics of a sample that I removed and try to digest w peroxide & hcl.
