Uses description - Mill scale

mixtures. Because the action of hydrochloric acid on both oxide scale and base metal is exceedingly rapid, it must be used with extreme caution. Unlike sulphuric acid, however, hydrochloric acid produces ferric chloride which is a strong pitting agent. As the salt content builds up in the bath, pitting becomes quite rapid. For that reason ...
