That CAN'T be true! / Re: Re: How much steel can a kilogram of fluoroantimonic acid burn through?

If you heat most acids they become more potent, sulfuric is one of them. It can reduce many metals like aluminum in seconds or minutes once it is hot. But it does not effect steel 55 gallon drums very much even when hot.

Hot acid will chew up mild steel (the stuff drums are made from) quite nicely. Cast iron is only slowly attacked by concentrated sulphuric acid.
Reduction of the aluminum oxide coating occurs, and then the aluminum is oxidized once again, each time it removes a layer of the aluminum. Since an aluminum part can be totally eaten away in minutes, by the hot sulfuric acid solution that is held in a steel tank, a steel tank that lasts for about three months to six months. I would think that steel is not that effected by hot sulfuric acid. I used to cut and weld the 55 gallon drums for a carburetor rebuilding company.
